As far as I know most file-system don't differentiate between directories
and directories in that regard.

statvfs(2) will provide you with a "struct statvfs" which e.g. contains
these fields:

             fsfilcnt_t      f_files;  /* total file nodes in file system */
             fsfilcnt_t      f_ffree;  /* free file nodes in file system */
             fsfilcnt_t      f_favail; /* free file nodes avail to non-root */
             fsfilcnt_t      f_fresvd; /* file nodes reserved for root */

Please have a look statvfs(5) ("man 5 statvfs") for more details.

        Kind regards
