@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.
