BASENAME(3) BSD Library Functions Manual BASENAME(3)
NAME
basename -- return the last component of a pathname
LIBRARY
Standard C Library (libc, -lc)
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 path consists entirely of '/' characters, 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.
SEE ALSO
basename(1), dirname(3)
STANDARDS
o X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'')
o IEEE Std 1003.1-2001 (``POSIX.1'')
BUGS
If the length of the result is longer than PATH_MAX bytes (including the terminating nul), the result will be truncated.
The basename() function returns a pointer to static storage that may be overwritten by subsequent calls to basename(). This is not strictly
a bug; it is explicitly allowed by IEEE Std 1003.1-2001 (``POSIX.1'').
