/* NOTE: Because of the special way this file is used by <complex.h>, this
file must NOT be protected from multiple inclusion as header files
usually are.
This file provides prototype declarations for the math functions.
Most functions are declared using the macro:
__MATHCALL (NAME, (ARGS...));
This means there is a function `NAME' returning `double' and a function
`NAMEf' returning `float'. Each place `_Mdouble_' appears in the
prototype, that is actually `double' in the prototype for `NAME' and
`float' in the prototype for `NAMEf'. Reentrant variant functions are
called `NAME_r' and `NAMEf_r'.
Functions returning other types like `int' are declared using the macro:
__MATHDECL (TYPE, NAME, (ARGS...));
This is just like __MATHCALL but for a function returning `TYPE'
instead of `_Mdouble_'. In all of these cases, there is still
both a `NAME' and a `NAMEf' that takes `float' arguments. */

missing arguments, 'optopt' is set to the option letter, and '?' is

letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in 'optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU 'getopt'.
The argument '--' causes premature termination of argument
scanning, explicitly telling 'getopt' that there are no more
options.
If OPTS begins with '-', then non-option arguments are treated as
arguments to the option '\1'. This behavior is specific to the GNU
'getopt'. If OPTS begins with '+', or POSIXLY_CORRECT is set in
the environment, then do not permute arguments.
For standards compliance, the 'argv' argument has the type
char *const *, but this is inaccurate; if argument permutation is
enabled, the argv array (not the strings it points to) must be
writable. */

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

left unchanged if the option is not found.

a compiled-in constant, such as set a value from 'optarg', set the
option's 'flag' field to zero and its 'val' field to a nonzero

/* NOTE: Because of the special way this file is used by <math.h>, this
file must NOT be protected from multiple inclusion as header files
usually are.
This file provides prototype declarations for the math functions.
Most functions are declared using the macro:
__MATHCALL (NAME,[_r], (ARGS...));
This means there is a function `NAME' returning `double' and a function
`NAMEf' returning `float'. Each place `_Mdouble_' appears in the
prototype, that is actually `double' in the prototype for `NAME' and
`float' in the prototype for `NAMEf'. Reentrant variant functions are
called `NAME_r' and `NAMEf_r'.
Functions returning other types like `int' are declared using the macro:
__MATHDECL (TYPE, NAME,[_r], (ARGS...));
This is just like __MATHCALL but for a function returning `TYPE'
instead of `_Mdouble_'. In all of these cases, there is still
both a `NAME' and a `NAMEf' that takes `float' arguments.
Note that there must be no whitespace before the argument passed for
NAME, to make token pasting work with -traditional. */
