NAME

basenameextract the base portion of a pathname

SYNOPSIS

#include <libgen.h>
char *
basename(const char *path);

DESCRIPTION

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.

RETURN VALUES

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.

ERRORS

The following error codes may be set in errno:
 
 
[ENAMETOOLONG]
The path component to be returned was larger than PATH_MAX.

HISTORY

The basename() function first appeared in OpenBSD 2.2.

CAVEATS

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.
