basename(3C)
NAME
basename − return the last element of a path name
SYNOPSIS
#include <libgen.h>
char ∗basename(char ∗path);
DESCRIPTION
The basename() function takes the pathname pointed to by path and returns a pointer to the final component of the pathname, deleting any trailing ’/’ characters.
If the string consists entirely of the ’/’ character, basename() returns a pointer to the string "/" .
If path is a null pointer or points to an empty string, basename() returns a pointer to the string "." .
RETURN VALUES
The basename() function returns a pointer to the final component of path.
EXAMPLES
| Input String | Output String |
| "/usr/lib" | "lib" |
| "/usr/" | "usr" |
| "/" | "/" |
USAGE
The basename() function may modify the string pointed to by path, and may return a pointer to static storage that may then be overwritten by a subsequent call to basename().
