-.Fn basename "const char *path"
-.Ft char *
-.Fn basename_r "const char *path" "char *bname"
-.Sh DESCRIPTION
-The
-.Fn basename
-function
-returns the last component from the pathname pointed to by
-.Fa path ,
-deleting any trailing
-.Sq \&/
-characters.
-If
-.Fa path

-.Fa path
-is a null pointer or the empty string, a pointer to the string
-.Qq \&.
-is returned.
-.Pp
-The
-.Fn basename_r
-variation accepts a buffer of at least
-.Dv MAXPATHLEN
-bytes in which to store the resulting component.
-.Sh IMPLEMENTATION NOTES
-The
-.Fn basename
-function
-returns a pointer to internal storage space allocated on the first call
-that will be overwritten
-by subsequent calls.
-.Fn basename_r
-is therefore preferred for threaded applications.
-.Sh RETURN VALUES
-On successful completion,
-.Fn basename
-and
-.Fn basename_r
-return pointers to the last component of
-.Fa path .
-.Pp
-If they fail, a null pointer is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-The following error codes may be set in
-.Va errno :
-.Bl -tag -width Er
-.It Bq Er ENAMETOOLONG
-The path component to be returned was larger than
-.Dv MAXPATHLEN .
