     The acl_free() function returns the value 0 if successful; otherwise the value -1 is
     returned and the global variable errno is set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_free() function returns the value -1 and
     and sets errno to the corresponding value:

     [EINVAL]           The value of the argument obj_p is invalid.
