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.
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().
When compiling multithreaded applications, the
_REENTRANT flag must
be defined on the compile line. This flag should only be used in
multithreaded applications.
