NOTES
There are two different versions of basename() - the POSIX version
described above, and the GNU version, which one gets after
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <string.h>
The GNU version never modifies its argument, and returns the empty
string when path has a trailing slash, and in particular also when it
is "/". There is no GNU version of dirname().
With glibc, one gets the POSIX version of basename() when <libgen.h> is
included, and the GNU version otherwise.
