Is there a macro to get the basename and dirname of __FILE__?

[Peng Yu]

Hi,

__FILE__ is the full path of the file used at compile time.

$ cat a/test.c
#include <stdio.h>
int main() {
	puts(__FILE__);
	return 0;
}
$ gcc a/test.c
$ ./a.out
a/test.c

The following discussion says there is no way to get its basename and
dirname at compile time. Is it still the case?

Could <string.h> functions be used at compile time for __FILE__ since
__FILE__ is known at compile time anyway? Thanks.
