basename - return last element of pathname

Syntax	#include <libgen.h> char *basename (char *path);
Description	When basename() is passed a pointer to a null-terminated string which contains a pathname, basename() returns a pointer to the last element of path. Terminating slash (/) characters are deleted. If the passed string only consists of the ’/’ character, a pointer to the ’/’ string is returned. If path or *path is zero, a pointer to the ’.’ string is returned. basename() is not reentrant.
Return val.	Pointer to the last component of path.
Example	Input string Output pointer /usr/lib lib /usr/ usr / /
Notes	basename() works on the passed string. If necessary, the string is modified by overwriting terminating slashes (’/’) with '\0'.
