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
X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'') 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''). NetBSD 8.1 May 10, 2008 NetBSD 8.1
