| @node func | |
| @section 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. |
