.Dd May 10, 2008 .Dt BASENAME 3 .Os .Sh NAME .Nm basename .Nd return the last component of a pathname .Sh LIBRARY .Lb libc .Sh SYNOPSIS n libgen.h .Ft char * .Fn basename "char *path" .Sh DESCRIPTION The .Fn basename function takes the pathname pointed to by .Ar path and returns a pointer to the final component of the pathname, deleting any trailing .Sq / characters.
p If .Ar path consists entirely of .Sq / characters, .Fn basename returns a pointer to the string .Dq / .
p If .Ar path is a null pointer or points to an empty string, .Fn basename returns a pointer to the string .Dq . . .Sh RETURN VALUES The .Fn basename function returns a pointer to the final component of .Ar path . .Sh SEE ALSO .Xr basename 1 , .Xr dirname 3 .Sh STANDARDS l -bullet -compact t .St -xpg4.2 t .St -p1003.1-2001 .El .Sh BUGS If the length of the result is longer than .Dv PATH_MAX bytes
q including the terminating nul , the result will be truncated.
p The .Fn basename function returns a pointer to static storage that may be overwritten by subsequent calls to .Fn basename . This is not strictly a bug; it is explicitly allowed by .St -p1003.1-2001 .
