BASENAME(3) OpenBSD Programmer's Manual BASENAME(3)NAMEbasename - extract the base portion of a pathname
basename(const char *path);
The basename() function returns the last component from the pathname
pointed to by path, deleting any trailing `/' characters. If path
consists entirely of `/' characters, a pointer to the string "/" is
returned. If path is a null pointer or the empty string, a pointer to
the string "." is returned.

component of path.
If basename() fails, a null pointer is returned and the global variable
errno is set to indicate the error.
The following error codes may be set in errno:

be overwritten by subsequent calls.
Other vendor implementations of basename() may modify the contents of the
string passed to basename(); this should be taken into account when
writing code which calls this function if portability is desired.
