     basename - extract the base portion of a pathname

     #include <libgen.h>

     char *
     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.

     On successful completion, basename() returns a pointer to the last
     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:

		   The path component to be returned was larger than

     basename(1), dirname(1), dirname(3)

     The basename() function conforms to X/Open Portability Guide Issue 4.2

     The basename() function first appeared in OpenBSD 2.2.

     basename() returns a pointer to internal static storage space that will
     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.
