@node func
@section func
@mindex func
The @code{func} module makes sure that you can use the predefined
identifier @code{__func__} as defined by C99 in your code.
A small example is:
@smallexample
#include <config.h>
#include <stdio.h> /* for printf */
int main (void)
@{
printf ("%s: hello world\n", __func__);
@}
@end smallexample
Note that @code{sizeof} cannot be applied to @code{__func__}: On SunPRO C
compiler, @code{sizeof __func__} evaluates to 0.
