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'').
