basename - extract the base portion of a pathname
basename(const char *path);
The basename() function returns the last component from the
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
If basename() fails, a null pointer is returned and the
errno is set to indicate the error.
The following error codes may be set in errno:
The path component to be returned was larger

space that will
be overwritten by subsequent calls.
