/* 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. */
