38.5 POSIX Thread Tunables
==========================
-- Tunable namespace: glibc.pthread
The behavior of POSIX threads can be tuned to gain performance
improvements according to specific hardware capabilities and
workload characteristics by setting the following tunables in the
‘pthread’ namespace:
-- Tunable: glibc.pthread.mutex_spin_count
The ‘glibc.pthread.mutex_spin_count’ tunable sets the maximum
number of times a thread should spin on the lock before calling
into the kernel to block. Adaptive spin is used for mutexes
initialized with the ‘PTHREAD_MUTEX_ADAPTIVE_NP’ GNU extension. It
affects both ‘pthread_mutex_lock’ and ‘pthread_mutex_timedlock’.
The thread spins until either the maximum spin count is reached or
the lock is acquired.
The default value of this tunable is ‘100’.
-- Tunable: glibc.pthread.stack_cache_size
This tunable configures the maximum size of the stack cache. Once
the stack cache exceeds this size, unused thread stacks are
returned to the kernel, to bring the cache size below this limit.
The value is measured in bytes. The default is ‘41943040’ (fourty
mibibytes).
-- Tunable: glibc.pthread.rseq
The ‘glibc.pthread.rseq’ tunable can be set to ‘0’, to disable
restartable sequences support in the GNU C Library. This enables
applications to perform direct restartable sequence registration
with the kernel. The default is ‘1’, which means that the GNU C
Library performs registration on behalf of the application.
Restartable sequences are a Linux-specific extension.

File: libc.info, Node: Hardware Capability Tunables, Next: Memory Related Tunables, Prev: POSIX Thread Tunables, Up: Tunables
38.6 Hardware Capability Tunables
=================================
-- Tunable namespace: glibc.cpu
Behavior of the GNU C Library can be tuned to assume specific
hardware capabilities by setting the following tunables in the
‘cpu’ namespace:
-- Tunable: glibc.cpu.hwcap_mask
This tunable supersedes the ‘LD_HWCAP_MASK’ environment variable
and is identical in features.
The ‘AT_HWCAP’ key in the Auxiliary Vector specifies instruction
set extensions available in the processor at runtime for some
architectures. The ‘glibc.cpu.hwcap_mask’ tunable allows the user
to mask out those capabilities at runtime, thus disabling use of
those extensions.
-- Tunable: glibc.cpu.hwcaps
The ‘glibc.cpu.hwcaps=-xxx,yyy,-zzz...’ tunable allows the user to
enable CPU/ARCH feature ‘yyy’, disable CPU/ARCH feature ‘xxx’ and
‘zzz’ where the feature name is case-sensitive and has to match the
ones in ‘sysdeps/x86/include/cpu-features.h’.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.cached_memopt
The ‘glibc.cpu.cached_memopt=[0|1]’ tunable allows the user to
enable optimizations recommended for cacheable memory. If set to
‘1’, the GNU C Library assumes that the process memory image
consists of cacheable (non-device) memory only. The default, ‘0’,
indicates that the process may use device memory.
This tunable is specific to powerpc, powerpc64 and powerpc64le.
-- Tunable: glibc.cpu.name
The ‘glibc.cpu.name=xxx’ tunable allows the user to tell the GNU C
Library to assume that the CPU is ‘xxx’ where xxx may have one of
these values: ‘generic’, ‘falkor’, ‘thunderxt88’, ‘thunderx2t99’,
‘thunderx2t99p1’, ‘ares’, ‘emag’, ‘kunpeng’, ‘a64fx’.
This tunable is specific to aarch64.
-- Tunable: glibc.cpu.x86_data_cache_size
The ‘glibc.cpu.x86_data_cache_size’ tunable allows the user to set
data cache size in bytes for use in memory and string routines.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.x86_shared_cache_size
The ‘glibc.cpu.x86_shared_cache_size’ tunable allows the user to
set shared cache size in bytes for use in memory and string
routines.
-- Tunable: glibc.cpu.x86_non_temporal_threshold
The ‘glibc.cpu.x86_non_temporal_threshold’ tunable allows the user
to set threshold in bytes for non temporal store. Non temporal
stores give a hint to the hardware to move data directly to memory
without displacing other data from the cache. This tunable is used
by some platforms to determine when to use non temporal stores in
operations like memmove and memcpy.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.x86_rep_movsb_threshold
The ‘glibc.cpu.x86_rep_movsb_threshold’ tunable allows the user to
set threshold in bytes to start using "rep movsb". The value must
be greater than zero, and currently defaults to 2048 bytes.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.x86_rep_stosb_threshold
The ‘glibc.cpu.x86_rep_stosb_threshold’ tunable allows the user to
set threshold in bytes to start using "rep stosb". The value must
be greater than zero, and currently defaults to 2048 bytes.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.x86_ibt
The ‘glibc.cpu.x86_ibt’ tunable allows the user to control how
indirect branch tracking (IBT) should be enabled. Accepted values
are ‘on’, ‘off’, and ‘permissive’. ‘on’ always turns on IBT
regardless of whether IBT is enabled in the executable and its
dependent shared libraries. ‘off’ always turns off IBT regardless
of whether IBT is enabled in the executable and its dependent
shared libraries. ‘permissive’ is the same as the default which
disables IBT on non-CET executables and shared libraries.
This tunable is specific to i386 and x86-64.
-- Tunable: glibc.cpu.x86_shstk
The ‘glibc.cpu.x86_shstk’ tunable allows the user to control how
the shadow stack (SHSTK) should be enabled. Accepted values are
‘on’, ‘off’, and ‘permissive’. ‘on’ always turns on SHSTK
regardless of whether SHSTK is enabled in the executable and its
dependent shared libraries. ‘off’ always turns off SHSTK
regardless of whether SHSTK is enabled in the executable and its
dependent shared libraries. ‘permissive’ changes how dlopen works
on non-CET shared libraries. By default, when SHSTK is enabled,
dlopening a non-CET shared library returns an error. With
‘permissive’, it turns off SHSTK instead.
This tunable is specific to i386 and x86-64.

38.7 Memory Related Tunables
============================
-- Tunable namespace: glibc.mem
This tunable namespace supports operations that affect the way the
GNU C Library and the process manage memory.
-- Tunable: glibc.mem.tagging
If the hardware supports memory tagging, this tunable can be used
to control the way the GNU C Library uses this feature. At present
this is only supported on AArch64 systems with the MTE extention;
it is ignored for all other systems.
This tunable takes a value between 0 and 255 and acts as a bitmask
that enables various capabilities.
Bit 0 (the least significant bit) causes the ‘malloc’ subsystem to
allocate tagged memory, with each allocation being assigned a
random tag.
Bit 1 enables precise faulting mode for tag violations on systems
that support deferred tag violation reporting. This may cause
programs to run more slowly.
Bit 2 enables either precise or deferred faulting mode for tag
violations whichever is preferred by the system.
Other bits are currently reserved.
The GNU C Library startup code will automatically enable memory
tagging support in the kernel if this tunable has any non-zero
value.
The default value is ‘0’, which disables all memory tagging.

Some of the facilities implemented by the C library really should be
thought of as parts of the C language itself. These facilities ought to
be documented in the C Language Manual, not in the library manual; but
since we don’t have the language manual yet, and documentation for these
features has been written, we are publishing it here.

* Data Type Measurements:: Parameters of data type representations.

File: libc.info, Node: Consistency Checking, Next: Variadic Functions, Up: Language Features
A.1 Explicitly Checking Internal Consistency
============================================
When you’re writing a program, it’s often a good idea to put in checks
at strategic places for “impossible” errors or violations of basic
assumptions. These kinds of checks are helpful in debugging problems
with the interfaces between different parts of the program, for example.
The ‘assert’ macro, defined in the header file ‘assert.h’, provides a
convenient way to abort the program while printing a message about where
in the program the error was detected.
Once you think your program is debugged, you can disable the error
checks performed by the ‘assert’ macro by recompiling with the macro
‘NDEBUG’ defined. This means you don’t actually have to change the
program source code to disable these checks.
But disabling these consistency checks is undesirable unless they
make the program significantly slower. All else being equal, more error
checking is good no matter who is running the program. A wise user
would rather have a program crash, visibly, than have it return nonsense
without indicating anything might be wrong.
-- Macro: void assert (int EXPRESSION)
Preliminary: | MT-Safe | AS-Unsafe heap corrupt | AC-Unsafe mem
lock corrupt | *Note POSIX Safety Concepts::.
Verify the programmer’s belief that EXPRESSION is nonzero at this
point in the program.
If ‘NDEBUG’ is not defined, ‘assert’ tests the value of EXPRESSION.
If it is false (zero), ‘assert’ aborts the program (*note Aborting
a Program::) after printing a message of the form:
FILE:LINENUM: FUNCTION: Assertion `EXPRESSION' failed.
on the standard error stream ‘stderr’ (*note Standard Streams::).
The filename and line number are taken from the C preprocessor
macros ‘__FILE__’ and ‘__LINE__’ and specify where the call to
‘assert’ was made. When using the GNU C compiler, the name of the
function which calls ‘assert’ is taken from the built-in variable
‘__PRETTY_FUNCTION__’; with older compilers, the function name and
following colon are omitted.
If the preprocessor macro ‘NDEBUG’ is defined before ‘assert.h’ is
included, the ‘assert’ macro is defined to do absolutely nothing.
*Warning:* Even the argument expression EXPRESSION is not evaluated
if ‘NDEBUG’ is in effect. So never use ‘assert’ with arguments
that involve side effects. For example, ‘assert (++i > 0);’ is a
bad idea, because ‘i’ will not be incremented if ‘NDEBUG’ is
defined.
Sometimes the “impossible” condition you want to check for is an
error return from an operating system function. Then it is useful to
display not only where the program crashes, but also what error was
returned. The ‘assert_perror’ macro makes this easy.
-- Macro: void assert_perror (int ERRNUM)
Preliminary: | MT-Safe | AS-Unsafe heap corrupt | AC-Unsafe mem
lock corrupt | *Note POSIX Safety Concepts::.
Similar to ‘assert’, but verifies that ERRNUM is zero.
If ‘NDEBUG’ is not defined, ‘assert_perror’ tests the value of
ERRNUM. If it is nonzero, ‘assert_perror’ aborts the program after
printing a message of the form:
FILE:LINENUM: FUNCTION: ERROR TEXT
on the standard error stream. The file name, line number, and
function name are as for ‘assert’. The error text is the result of
‘strerror (ERRNUM)’. *Note Error Messages::.
Like ‘assert’, if ‘NDEBUG’ is defined before ‘assert.h’ is
included, the ‘assert_perror’ macro does absolutely nothing. It
does not evaluate the argument, so ERRNUM should not have any side
effects. It is best for ERRNUM to be just a simple variable
reference; often it will be ‘errno’.
This macro is a GNU extension.
*Usage note:* The ‘assert’ facility is designed for detecting
_internal inconsistency_; it is not suitable for reporting invalid input
or improper usage by the _user_ of the program.
The information in the diagnostic messages printed by the ‘assert’
and ‘assert_perror’ macro is intended to help you, the programmer, track
down the cause of a bug, but is not really useful for telling a user of
your program why his or her input was invalid or why a command could not
be carried out. What’s more, your program should not abort when given
invalid input, as ‘assert’ would do—it should exit with nonzero status
(*note Exit Status::) after printing its error messages, or perhaps read
another command or move on to the next input file.
*Note Error Messages::, for information on printing error messages
for problems that _do not_ represent bugs in the program.

A.2 Variadic Functions
======================
ISO C defines a syntax for declaring a function to take a variable
number or type of arguments. (Such functions are referred to as
"varargs functions" or "variadic functions".) However, the language
itself provides no mechanism for such functions to access their
non-required arguments; instead, you use the variable arguments macros
defined in ‘stdarg.h’.
This section describes how to declare variadic functions, how to
write them, and how to call them properly.
*Compatibility Note:* Many older C dialects provide a similar, but
incompatible, mechanism for defining functions with variable numbers of
arguments, using ‘varargs.h’.
* Menu:
* Why Variadic:: Reasons for making functions take
variable arguments.
* How Variadic:: How to define and call variadic functions.
* Variadic Example:: A complete example.

File: libc.info, Node: Why Variadic, Next: How Variadic, Up: Variadic Functions
A.2.1 Why Variadic Functions are Used
-------------------------------------
Ordinary C functions take a fixed number of arguments. When you define
a function, you specify the data type for each argument. Every call to
the function should supply the expected number of arguments, with types
that can be converted to the specified ones. Thus, if the function
‘foo’ is declared with ‘int foo (int, char *);’ then you must call it
with two arguments, a number (any kind will do) and a string pointer.
But some functions perform operations that can meaningfully accept an
unlimited number of arguments.
In some cases a function can handle any number of values by operating
on all of them as a block. For example, consider a function that
allocates a one-dimensional array with ‘malloc’ to hold a specified set
of values. This operation makes sense for any number of values, as long
as the length of the array corresponds to that number. Without
facilities for variable arguments, you would have to define a separate
function for each possible array size.
The library function ‘printf’ (*note Formatted Output::) is an
example of another class of function where variable arguments are
useful. This function prints its arguments (which can vary in type as
well as number) under the control of a format template string.
These are good reasons to define a "variadic" function which can
handle as many arguments as the caller chooses to pass.
Some functions such as ‘open’ take a fixed set of arguments, but
occasionally ignore the last few. Strict adherence to ISO C requires
these functions to be defined as variadic; in practice, however, the GNU
C compiler and most other C compilers let you define such a function to
take a fixed set of arguments—the most it can ever use—and then only
_declare_ the function as variadic (or not declare its arguments at
all!).

A.2.2 How Variadic Functions are Defined and Used
-------------------------------------------------
Defining and using a variadic function involves three steps:
• _Define_ the function as variadic, using an ellipsis (‘…’) in the
argument list, and using special macros to access the variable
arguments. *Note Receiving Arguments::.
• _Declare_ the function as variadic, using a prototype with an
ellipsis (‘…’), in all the files which call it. *Note Variadic
Prototypes::.
• _Call_ the function by writing the fixed arguments followed by the
additional variable arguments. *Note Calling Variadics::.
* Menu:

optional argument values.

variable arguments functions.
* Argument Macros:: Detailed specification of the macros

File: libc.info, Node: Variadic Prototypes, Next: Receiving Arguments, Up: How Variadic
A.2.2.1 Syntax for Variable Arguments
.....................................
A function that accepts a variable number of arguments must be declared
with a prototype that says so. You write the fixed arguments as usual,
and then tack on ‘…’ to indicate the possibility of additional
arguments. The syntax of ISO C requires at least one fixed argument
before the ‘…’. For example,
int
func (const char *a, int b, …)
{
…
}
defines a function ‘func’ which returns an ‘int’ and takes two required
arguments, a ‘const char *’ and an ‘int’. These are followed by any
number of anonymous arguments.
*Portability note:* For some C compilers, the last required argument
must not be declared ‘register’ in the function definition.
Furthermore, this argument’s type must be "self-promoting": that is, the
default promotions must not change its type. This rules out array and
function types, as well as ‘float’, ‘char’ (whether signed or not) and ‘short int’
(whether signed or not). This is actually an ISO C requirement.

File: libc.info, Node: Receiving Arguments, Next: How Many Arguments, Prev: Variadic Prototypes, Up: How Variadic
A.2.2.2 Receiving the Argument Values
.....................................
Ordinary fixed arguments have individual names, and you can use these
names to access their values. But optional arguments have no
names—nothing but ‘…’. How can you access them?
The only way to access them is sequentially, in the order they were
written, and you must use special macros from ‘stdarg.h’ in the
following three step process:
1. You initialize an argument pointer variable of type ‘va_list’ using
‘va_start’. The argument pointer when initialized points to the
first optional argument.
2. You access the optional arguments by successive calls to ‘va_arg’.
The first call to ‘va_arg’ gives you the first optional argument,
the next call gives you the second, and so on.
You can stop at any time if you wish to ignore any remaining
optional arguments. It is perfectly all right for a function to
access fewer arguments than were supplied in the call, but you will
get garbage values if you try to access too many arguments.
3. You indicate that you are finished with the argument pointer
variable by calling ‘va_end’.
(In practice, with most C compilers, calling ‘va_end’ does nothing.
This is always true in the GNU C compiler. But you might as well
call ‘va_end’ just in case your program is someday compiled with a
peculiar compiler.)
*Note Argument Macros::, for the full definitions of ‘va_start’,
‘va_arg’ and ‘va_end’.
Steps 1 and 3 must be performed in the function that accepts the
optional arguments. However, you can pass the ‘va_list’ variable as an
argument to another function and perform all or part of step 2 there.
You can perform the entire sequence of three steps multiple times
within a single function invocation. If you want to ignore the optional
arguments, you can do these steps zero times.
You can have more than one argument pointer variable if you like.
You can initialize each variable with ‘va_start’ when you wish, and then
you can fetch arguments with each argument pointer as you wish. Each
argument pointer variable will sequence through the same set of argument
values, but at its own pace.
*Portability note:* With some compilers, once you pass an argument
pointer value to a subroutine, you must not keep using the same argument
pointer value after that subroutine returns. For full portability, you
should just pass it to ‘va_end’. This is actually an ISO C requirement,
but most ANSI C compilers work happily regardless.

File: libc.info, Node: How Many Arguments, Next: Calling Variadics, Prev: Receiving Arguments, Up: How Variadic
A.2.2.3 How Many Arguments Were Supplied
........................................
There is no general way for a function to determine the number and type
of the optional arguments it was called with. So whoever designs the
function typically designs a convention for the caller to specify the
number and type of arguments. It is up to you to define an appropriate
calling convention for each variadic function, and write all calls
accordingly.
One kind of calling convention is to pass the number of optional
arguments as one of the fixed arguments. This convention works provided
all of the optional arguments are of the same type.
A similar alternative is to have one of the required arguments be a
bit mask, with a bit for each possible purpose for which an optional
argument might be supplied. You would test the bits in a predefined
sequence; if the bit is set, fetch the value of the next argument,
otherwise use a default value.
A required argument can be used as a pattern to specify both the
number and types of the optional arguments. The format string argument
to ‘printf’ is one example of this (*note Formatted Output Functions::).
Another possibility is to pass an “end marker” value as the last
optional argument. For example, for a function that manipulates an
arbitrary number of pointer arguments, a null pointer might indicate the
end of the argument list. (This assumes that a null pointer isn’t
otherwise meaningful to the function.) The ‘execl’ function works in
just this way; see *note Executing a File::.

File: libc.info, Node: Calling Variadics, Next: Argument Macros, Prev: How Many Arguments, Up: How Variadic
A.2.2.4 Calling Variadic Functions
..................................
You don’t have to do anything special to call a variadic function. Just
put the arguments (required arguments, followed by optional ones) inside
parentheses, separated by commas, as usual. But you must declare the
function with a prototype and know how the argument values are
converted.
In principle, functions that are _defined_ to be variadic must also
be _declared_ to be variadic using a function prototype whenever you
call them. (*Note Variadic Prototypes::, for how.) This is because
some C compilers use a different calling convention to pass the same set
of argument values to a function depending on whether that function
takes variable arguments or fixed arguments.
In practice, the GNU C compiler always passes a given set of argument
types in the same way regardless of whether they are optional or
required. So, as long as the argument types are self-promoting, you can
safely omit declaring them. Usually it is a good idea to declare the
argument types for variadic functions, and indeed for all functions.
But there are a few functions which it is extremely convenient not to
have to declare as variadic—for example, ‘open’ and ‘printf’.
Since the prototype doesn’t specify types for optional arguments, in
a call to a variadic function the "default argument promotions" are
performed on the optional argument values. This means the objects of
type ‘char’ or ‘short int’ (whether signed or not) are promoted to
either ‘int’ or ‘unsigned int’, as appropriate; and that objects of type
‘float’ are promoted to type ‘double’. So, if the caller passes a
‘char’ as an optional argument, it is promoted to an ‘int’, and the
function can access it with ‘va_arg (AP, int)’.
Conversion of the required arguments is controlled by the function
prototype in the usual way: the argument expression is converted to the
declared argument type as if it were being assigned to a variable of
that type.

File: libc.info, Node: Argument Macros, Prev: Calling Variadics, Up: How Variadic
A.2.2.5 Argument Access Macros
..............................
Here are descriptions of the macros used to retrieve variable arguments.
These macros are defined in the header file ‘stdarg.h’.
-- Data Type: va_list
The type ‘va_list’ is used for argument pointer variables.
-- Macro: void va_start (va_list AP, LAST-REQUIRED)
Preliminary: | MT-Safe | AS-Safe | AC-Safe | *Note POSIX Safety
Concepts::.
This macro initializes the argument pointer variable AP to point to
the first of the optional arguments of the current function;
LAST-REQUIRED must be the last required argument to the function.
-- Macro: TYPE va_arg (va_list AP, TYPE)
Preliminary: | MT-Safe race:ap | AS-Safe | AC-Unsafe corrupt |
*Note POSIX Safety Concepts::.
The ‘va_arg’ macro returns the value of the next optional argument,
and modifies the value of AP to point to the subsequent argument.
Thus, successive uses of ‘va_arg’ return successive optional
arguments.
The type of the value returned by ‘va_arg’ is TYPE as specified in
the call. TYPE must be a self-promoting type (not ‘char’ or ‘short
int’ or ‘float’) that matches the type of the actual argument.
-- Macro: void va_end (va_list AP)
Preliminary: | MT-Safe | AS-Safe | AC-Safe | *Note POSIX Safety
Concepts::.
This ends the use of AP. After a ‘va_end’ call, further ‘va_arg’
calls with the same AP may not work. You should invoke ‘va_end’
before returning from the function in which ‘va_start’ was invoked
with the same AP argument.
In the GNU C Library, ‘va_end’ does nothing, and you need not ever
use it except for reasons of portability.
Sometimes it is necessary to parse the list of parameters more than
once or one wants to remember a certain position in the parameter list.
To do this, one will have to make a copy of the current value of the
argument. But ‘va_list’ is an opaque type and one cannot necessarily
assign the value of one variable of type ‘va_list’ to another variable
of the same type.
-- Macro: void va_copy (va_list DEST, va_list SRC)
-- Macro: void __va_copy (va_list DEST, va_list SRC)
Preliminary: | MT-Safe | AS-Safe | AC-Safe | *Note POSIX Safety
Concepts::.
The ‘va_copy’ macro allows copying of objects of type ‘va_list’
even if this is not an integral type. The argument pointer in DEST
is initialized to point to the same argument as the pointer in SRC.
‘va_copy’ was added in ISO C99. When building for strict
conformance to ISO C90 (‘gcc -std=c90’), it is not available. GCC
provides ‘__va_copy’, as an extension, in any standards mode;
before GCC 3.0, it was the only macro for this functionality.
These macros are no longer provided by the GNU C Library, but
rather by the compiler.
If you want to use ‘va_copy’ and be portable to pre-C99 systems, you
should always be prepared for the possibility that this macro will not
be available. On architectures where a simple assignment is invalid,
hopefully ‘va_copy’ _will_ be available, so one should always write
something like this if concerned about pre-C99 portability:
{
va_list ap, save;
…
#ifdef va_copy
va_copy (save, ap);
#else
save = ap;
#endif
…
}

A.2.3 Example of a Variadic Function
------------------------------------
Here is a complete sample function that accepts a variable number of
arguments. The first argument to the function is the count of remaining
arguments, which are added up and the result returned. While trivial,
this function is sufficient to illustrate how to use the variable
arguments facility.
#include <stdarg.h>
#include <stdio.h>
int
add_em_up (int count,...)
{
va_list ap;
int i, sum;
va_start (ap, count); /* Initialize the argument list. */
sum = 0;
for (i = 0; i < count; i++)
sum += va_arg (ap, int); /* Get the next argument value. */
va_end (ap); /* Clean up. */
return sum;
}
int
main (void)
{
/* This call prints 16. */
printf ("%d\n", add_em_up (3, 5, 5, 6));
/* This call prints 55. */
printf ("%d\n", add_em_up (10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10));
return 0;
}

File: libc.info, Node: Null Pointer Constant, Next: Important Data Types, Prev: Variadic Functions, Up: Language Features
A.3 Null Pointer Constant
=========================
The null pointer constant is guaranteed not to point to any real object.
You can assign it to any pointer variable since it has type ‘void *’.
The preferred way to write a null pointer constant is with ‘NULL’.
-- Macro: void * NULL
This is a null pointer constant.
You can also use ‘0’ or ‘(void *)0’ as a null pointer constant, but
using ‘NULL’ is cleaner because it makes the purpose of the constant
more evident.
If you use the null pointer constant as a function argument, then for
complete portability you should make sure that the function has a
prototype declaration. Otherwise, if the target machine has two
different pointer representations, the compiler won’t know which
representation to use for that argument. You can avoid the problem by
explicitly casting the constant to the proper pointer type, but we
recommend instead adding a prototype for the function you are calling.

File: libc.info, Node: Important Data Types, Next: Data Type Measurements, Prev: Null Pointer Constant, Up: Language Features
A.4 Important Data Types
========================
The result of subtracting two pointers in C is always an integer, but
the precise data type varies from C compiler to C compiler. Likewise,
the data type of the result of ‘sizeof’ also varies between compilers.
ISO C defines standard aliases for these two types, so you can refer to
them in a portable fashion. They are defined in the header file
‘stddef.h’.
-- Data Type: ptrdiff_t
This is the signed integer type of the result of subtracting two
pointers. For example, with the declaration ‘char *p1, *p2;’, the
expression ‘p2 - p1’ is of type ‘ptrdiff_t’. This will probably be
one of the standard signed integer types (‘short int’, ‘int’ or
‘long int’), but might be a nonstandard type that exists only for
this purpose.
-- Data Type: size_t
This is an unsigned integer type used to represent the sizes of
objects. The result of the ‘sizeof’ operator is of this type, and
functions such as ‘malloc’ (*note Unconstrained Allocation::) and
‘memcpy’ (*note Copying Strings and Arrays::) accept arguments of
this type to specify object sizes. On systems using the GNU C
Library, this will be ‘unsigned int’ or ‘unsigned long int’.
*Usage Note:* ‘size_t’ is the preferred way to declare any
arguments or variables that hold the size of an object.
*Compatibility Note:* Implementations of C before the advent of ISO C
generally used ‘unsigned int’ for representing object sizes and ‘int’
for pointer subtraction results. They did not necessarily define either
‘size_t’ or ‘ptrdiff_t’. Unix systems did define ‘size_t’, in
‘sys/types.h’, but the definition was usually a signed type.

A.5 Data Type Measurements
==========================
Most of the time, if you choose the proper C data type for each object
in your program, you need not be concerned with just how it is
represented or how many bits it uses. When you do need such
information, the C language itself does not provide a way to get it.
The header files ‘limits.h’ and ‘float.h’ contain macros which give you
this information in full detail.
* Menu:
* Width of Type:: How many bits does an integer type hold?
* Range of Type:: What are the largest and smallest values
that an integer type can hold?
* Floating Type Macros:: Parameters that measure the floating point types.
* Structure Measurement:: Getting measurements on structure types.

File: libc.info, Node: Width of Type, Next: Range of Type, Up: Data Type Measurements
A.5.1 Width of an Integer Type
------------------------------
TS 18661-1:2014 defines macros for the width of integer types (the
number of value and sign bits). One benefit of these macros is they can
be used in ‘#if’ preprocessor directives, whereas ‘sizeof’ cannot. The
following macros are defined in ‘limits.h’.
‘CHAR_WIDTH’
‘SCHAR_WIDTH’
‘UCHAR_WIDTH’
‘SHRT_WIDTH’
‘USHRT_WIDTH’
‘INT_WIDTH’
‘UINT_WIDTH’
‘LONG_WIDTH’
‘ULONG_WIDTH’
‘LLONG_WIDTH’
‘ULLONG_WIDTH’
These are the widths of the types ‘char’, ‘signed char’, ‘unsigned
char’, ‘short int’, ‘unsigned short int’, ‘int’, ‘unsigned int’,
‘long int’, ‘unsigned long int’, ‘long long int’ and ‘unsigned long
long int’, respectively.
Further such macros are defined in ‘stdint.h’. Apart from those for
types specified by width (*note Integers::), the following are defined:
‘INTPTR_WIDTH’
‘UINTPTR_WIDTH’
‘PTRDIFF_WIDTH’
‘SIG_ATOMIC_WIDTH’
‘SIZE_WIDTH’
‘WCHAR_WIDTH’
‘WINT_WIDTH’
These are the widths of the types ‘intptr_t’, ‘uintptr_t’,
‘ptrdiff_t’, ‘sig_atomic_t’, ‘size_t’, ‘wchar_t’ and ‘wint_t’,
respectively.
A common reason that a program needs to know how many bits are in an
integer type is for using an array of ‘unsigned long int’ as a bit
vector. You can access the bit at index N with:
vector[N / ULONG_WIDTH] & (1UL << (N % ULONG_WIDTH))
Before ‘ULONG_WIDTH’ was a part of the C language, ‘CHAR_BIT’ was
used to compute the number of bits in an integer data type.
-- Macro: int CHAR_BIT
This is the number of bits in a ‘char’. POSIX.1-2001 requires this
to be 8.
The number of bits in any data type TYPE can be computed like this:
sizeof (TYPE) * CHAR_BIT
That expression includes padding bits as well as value and sign bits.
On all systems supported by the GNU C Library, standard integer types
other than ‘_Bool’ do not have any padding bits.
*Portability Note:* One cannot actually easily compute the number of
usable bits in a portable manner.

A.5.2 Range of an Integer Type
------------------------------
Suppose you need to store an integer value which can range from zero to
one million. Which is the smallest type you can use? There is no
general rule; it depends on the C compiler and target machine. You can
use the ‘MIN’ and ‘MAX’ macros in ‘limits.h’ to determine which type
will work.
Each signed integer type has a pair of macros which give the smallest
and largest values that it can hold. Each unsigned integer type has one
such macro, for the maximum value; the minimum value is, of course,
zero.
The values of these macros are all integer constant expressions. The
‘MAX’ and ‘MIN’ macros for ‘char’ and ‘short int’ types have values of
type ‘int’. The ‘MAX’ and ‘MIN’ macros for the other types have values
of the same type described by the macro—thus, ‘ULONG_MAX’ has type
‘unsigned long int’.
‘SCHAR_MIN’
This is the minimum value that can be represented by a
‘signed char’.
‘SCHAR_MAX’
‘UCHAR_MAX’
These are the maximum values that can be represented by a ‘signed char’
and ‘unsigned char’, respectively.
‘CHAR_MIN’
This is the minimum value that can be represented by a ‘char’.
It’s equal to ‘SCHAR_MIN’ if ‘char’ is signed, or zero otherwise.
‘CHAR_MAX’
This is the maximum value that can be represented by a ‘char’.
It’s equal to ‘SCHAR_MAX’ if ‘char’ is signed, or ‘UCHAR_MAX’
otherwise.
‘SHRT_MIN’
This is the minimum value that can be represented by a
‘signed short int’. On most machines that the GNU C Library runs
on, ‘short’ integers are 16-bit quantities.
‘SHRT_MAX’
‘USHRT_MAX’
These are the maximum values that can be represented by a ‘signed short int’
and ‘unsigned short int’, respectively.
‘INT_MIN’
This is the minimum value that can be represented by a
‘signed int’. On most machines that the GNU C Library runs on, an
‘int’ is a 32-bit quantity.
‘INT_MAX’
‘UINT_MAX’
These are the maximum values that can be represented by,
respectively, the type ‘signed int’ and the type ‘unsigned int’.
‘LONG_MIN’
This is the minimum value that can be represented by a
‘signed long int’. On most machines that the GNU C Library runs
on, ‘long’ integers are 32-bit quantities, the same size as ‘int’.

‘ULONG_MAX’
These are the maximum values that can be represented by a ‘signed long int’

This is the minimum value that can be represented by a
‘signed long long int’. On most machines that the GNU C Library
runs on, ‘long long’ integers are 64-bit quantities.

‘ULLONG_MAX’
These are the maximum values that can be represented by a ‘signed
long long int’ and ‘unsigned long long int’, respectively.
‘LONG_LONG_MIN’
‘LONG_LONG_MAX’
‘ULONG_LONG_MAX’
These are obsolete names for ‘LLONG_MIN’, ‘LLONG_MAX’, and
‘ULLONG_MAX’. They are only available if ‘_GNU_SOURCE’ is defined
(*note Feature Test Macros::). In GCC versions prior to 3.0, these
were the only names available.
‘WCHAR_MAX’
This is the maximum value that can be represented by a ‘wchar_t’.
*Note Extended Char Intro::.
The header file ‘limits.h’ also defines some additional constants
that parameterize various operating system and file system limits.
These constants are described in *note System Configuration::.

A.5.3 Floating Type Macros
--------------------------
The specific representation of floating point numbers varies from
machine to machine. Because floating point numbers are represented
internally as approximate quantities, algorithms for manipulating
floating point data often need to take account of the precise details of
the machine’s floating point representation.
Some of the functions in the C library itself need this information;
for example, the algorithms for printing and reading floating point
numbers (*note I/O on Streams::) and for calculating trigonometric and
irrational functions (*note Mathematics::) use it to avoid round-off
error and loss of accuracy. User programs that implement numerical
analysis techniques also often need this information in order to
minimize or compute error bounds.
The header file ‘float.h’ describes the format used by your machine.

A.5.3.1 Floating Point Representation Concepts
..............................................
This section introduces the terminology for describing floating point
representations.
You are probably already familiar with most of these concepts in
terms of scientific or exponential notation for floating point numbers.
For example, the number ‘123456.0’ could be expressed in exponential
notation as ‘1.23456e+05’, a shorthand notation indicating that the
mantissa ‘1.23456’ is multiplied by the base ‘10’ raised to power ‘5’.
More formally, the internal representation of a floating point number
can be characterized in terms of the following parameters:
• The "sign" is either ‘-1’ or ‘1’.
• The "base" or "radix" for exponentiation, an integer greater than
‘1’. This is a constant for a particular representation.
• The "exponent" to which the base is raised. The upper and lower
bounds of the exponent value are constants for a particular
representation.
Sometimes, in the actual bits representing the floating point
number, the exponent is "biased" by adding a constant to it, to
make it always be represented as an unsigned quantity. This is
only important if you have some reason to pick apart the bit fields
making up the floating point number by hand, which is something for
which the GNU C Library provides no support. So this is ignored in
the discussion that follows.
• The "mantissa" or "significand" is an unsigned integer which is a
part of each floating point number.
• The "precision" of the mantissa. If the base of the representation
is B, then the precision is the number of base-B digits in the
mantissa. This is a constant for a particular representation.
Many floating point representations have an implicit "hidden bit"
in the mantissa. This is a bit which is present virtually in the
mantissa, but not stored in memory because its value is always 1 in
a normalized number. The precision figure (see above) includes any
hidden bits.
Again, the GNU C Library provides no facilities for dealing with
such low-level aspects of the representation.
The mantissa of a floating point number represents an implicit
fraction whose denominator is the base raised to the power of the
precision. Since the largest representable mantissa is one less than
this denominator, the value of the fraction is always strictly less than
‘1’. The mathematical value of a floating point number is then the
product of this fraction, the sign, and the base raised to the exponent.
We say that the floating point number is "normalized" if the fraction
is at least ‘1/B’, where B is the base. In other words, the mantissa
would be too large to fit if it were multiplied by the base.
Non-normalized numbers are sometimes called "denormal"; they contain
less precision than the representation normally can hold.
If the number is not normalized, then you can subtract ‘1’ from the
exponent while multiplying the mantissa by the base, and get another
floating point number with the same value. "Normalization" consists of
doing this repeatedly until the number is normalized. Two distinct
normalized floating point numbers cannot be equal in value.
(There is an exception to this rule: if the mantissa is zero, it is
considered normalized. Another exception happens on certain machines
where the exponent is as small as the representation can hold. Then it
is impossible to subtract ‘1’ from the exponent, so a number may be
normalized even if its fraction is less than ‘1/B’.)

A.5.3.2 Floating Point Parameters
.................................
These macro definitions can be accessed by including the header file
‘float.h’ in your program.
Macro names starting with ‘FLT_’ refer to the ‘float’ type, while
names beginning with ‘DBL_’ refer to the ‘double’ type and names
beginning with ‘LDBL_’ refer to the ‘long double’ type. (If GCC does
not support ‘long double’ as a distinct data type on a target machine
then the values for the ‘LDBL_’ constants are equal to the corresponding
constants for the ‘double’ type.)
Of these macros, only ‘FLT_RADIX’ is guaranteed to be a constant
expression. The other macros listed here cannot be reliably used in
places that require constant expressions, such as ‘#if’ preprocessing
directives or in the dimensions of static arrays.
Although the ISO C standard specifies minimum and maximum values for
most of these parameters, the GNU C implementation uses whatever values
describe the floating point representation of the target machine. So in
principle GNU C actually satisfies the ISO C requirements only if the
target machine is suitable. In practice, all the machines currently
supported are suitable.
‘FLT_ROUNDS’
This value characterizes the rounding mode for floating point
addition. The following values indicate standard rounding modes:
‘-1’
The mode is indeterminable.
‘0’
Rounding is towards zero.
‘1’
Rounding is to the nearest number.
‘2’
Rounding is towards positive infinity.
‘3’
Rounding is towards negative infinity.
Any other value represents a machine-dependent nonstandard rounding
mode.
On most machines, the value is ‘1’, in accordance with the IEEE
standard for floating point.
Here is a table showing how certain values round for each possible
value of ‘FLT_ROUNDS’, if the other aspects of the representation
match the IEEE single-precision standard.
0 1 2 3
1.00000003 1.0 1.0 1.00000012 1.0
1.00000007 1.0 1.00000012 1.00000012 1.0
-1.00000003 -1.0 -1.0 -1.0 -1.00000012
-1.00000007 -1.0 -1.00000012 -1.0 -1.00000012
‘FLT_RADIX’
This is the value of the base, or radix, of the exponent
representation. This is guaranteed to be a constant expression,
unlike the other macros described in this section. The value is 2
on all machines we know of except the IBM 360 and derivatives.
‘FLT_MANT_DIG’
This is the number of base-‘FLT_RADIX’ digits in the floating point
mantissa for the ‘float’ data type. The following expression
yields ‘1.0’ (even though mathematically it should not) due to the
limited number of mantissa digits:
float radix = FLT_RADIX;
1.0f + 1.0f / radix / radix / … / radix
where ‘radix’ appears ‘FLT_MANT_DIG’ times.
‘DBL_MANT_DIG’
‘LDBL_MANT_DIG’
This is the number of base-‘FLT_RADIX’ digits in the floating point
mantissa for the data types ‘double’ and ‘long double’,
respectively.
‘FLT_DIG’
This is the number of decimal digits of precision for the ‘float’
data type. Technically, if P and B are the precision and base
(respectively) for the representation, then the decimal precision Q
is the maximum number of decimal digits such that any floating
point number with Q base 10 digits can be rounded to a floating
point number with P base B digits and back again, without change to
the Q decimal digits.
The value of this macro is supposed to be at least ‘6’, to satisfy
ISO C.
‘DBL_DIG’
‘LDBL_DIG’
These are similar to ‘FLT_DIG’, but for the data types ‘double’ and
‘long double’, respectively. The values of these macros are
supposed to be at least ‘10’.
‘FLT_MIN_EXP’
This is the smallest possible exponent value for type ‘float’.
More precisely, it is the minimum negative integer such that the
value ‘FLT_RADIX’ raised to this power minus 1 can be represented
as a normalized floating point number of type ‘float’.
‘DBL_MIN_EXP’
‘LDBL_MIN_EXP’
These are similar to ‘FLT_MIN_EXP’, but for the data types ‘double’
and ‘long double’, respectively.
‘FLT_MIN_10_EXP’
This is the minimum negative integer such that ‘10’ raised to this
power minus 1 can be represented as a normalized floating point
number of type ‘float’. This is supposed to be ‘-37’ or even less.
‘DBL_MIN_10_EXP’
‘LDBL_MIN_10_EXP’
These are similar to ‘FLT_MIN_10_EXP’, but for the data types
‘double’ and ‘long double’, respectively.
‘FLT_MAX_EXP’
This is the largest possible exponent value for type ‘float’. More
precisely, this is the maximum positive integer such that value
‘FLT_RADIX’ raised to this power minus 1 can be represented as a
floating point number of type ‘float’.
‘DBL_MAX_EXP’
‘LDBL_MAX_EXP’
These are similar to ‘FLT_MAX_EXP’, but for the data types ‘double’
and ‘long double’, respectively.
‘FLT_MAX_10_EXP’
This is the maximum positive integer such that ‘10’ raised to this
power minus 1 can be represented as a normalized floating point
number of type ‘float’. This is supposed to be at least ‘37’.
‘DBL_MAX_10_EXP’
‘LDBL_MAX_10_EXP’
These are similar to ‘FLT_MAX_10_EXP’, but for the data types
‘double’ and ‘long double’, respectively.
‘FLT_MAX’
The value of this macro is the maximum number representable in type
‘float’. It is supposed to be at least ‘1E+37’. The value has
type ‘float’.
The smallest representable number is ‘- FLT_MAX’.
‘DBL_MAX’
‘LDBL_MAX’
These are similar to ‘FLT_MAX’, but for the data types ‘double’ and
‘long double’, respectively. The type of the macro’s value is the
same as the type it describes.
‘FLT_MIN’
The value of this macro is the minimum normalized positive floating
point number that is representable in type ‘float’. It is supposed
to be no more than ‘1E-37’.
‘DBL_MIN’
‘LDBL_MIN’
These are similar to ‘FLT_MIN’, but for the data types ‘double’ and
‘long double’, respectively. The type of the macro’s value is the
same as the type it describes.
‘FLT_EPSILON’
This is the difference between 1 and the smallest floating point
number of type ‘float’ that is greater than 1. It’s supposed to be
no greater than ‘1E-5’.
‘DBL_EPSILON’
‘LDBL_EPSILON’
These are similar to ‘FLT_EPSILON’, but for the data types ‘double’
and ‘long double’, respectively. The type of the macro’s value is
the same as the type it describes. The values are not supposed to
be greater than ‘1E-9’.

A.5.3.3 IEEE Floating Point
...........................
Here is an example showing how the floating type measurements come out
for the most common floating point representation, specified by the
‘IEEE Standard for Binary Floating Point Arithmetic (ANSI/IEEE Std
754-1985)’. Nearly all computers designed since the 1980s use this
format.
The IEEE single-precision float representation uses a base of 2.
There is a sign bit, a mantissa with 23 bits plus one hidden bit (so the
total precision is 24 base-2 digits), and an 8-bit exponent that can
represent values in the range -125 to 128, inclusive.
So, for an implementation that uses this representation for the
‘float’ data type, appropriate values for the corresponding parameters
are:
FLT_RADIX 2
FLT_MANT_DIG 24
FLT_DIG 6
FLT_MIN_EXP -125
FLT_MIN_10_EXP -37
FLT_MAX_EXP 128
FLT_MAX_10_EXP +38
FLT_MIN 1.17549435E-38F
FLT_MAX 3.40282347E+38F
FLT_EPSILON 1.19209290E-07F
Here are the values for the ‘double’ data type:
DBL_MANT_DIG 53
DBL_DIG 15
DBL_MIN_EXP -1021
DBL_MIN_10_EXP -307
DBL_MAX_EXP 1024
DBL_MAX_10_EXP 308
DBL_MAX 1.7976931348623157E+308
DBL_MIN 2.2250738585072014E-308
DBL_EPSILON 2.2204460492503131E-016

A.5.4 Structure Field Offset Measurement
----------------------------------------
You can use ‘offsetof’ to measure the location within a structure type
of a particular structure member.
-- Macro: size_t offsetof (TYPE, MEMBER)
Preliminary: | MT-Safe | AS-Safe | AC-Safe | *Note POSIX Safety
Concepts::.
This expands to an integer constant expression that is the offset
of the structure member named MEMBER in the structure type TYPE.
For example, ‘offsetof (struct s, elem)’ is the offset, in bytes,
of the member ‘elem’ in a ‘struct s’.
This macro won’t work if MEMBER is a bit field; you get an error
from the C compiler in that case.
