Синопсис (Synopsis)

     int
     acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm);

Описание (Description)

The acl_delete_perm() function deletes the permission contained in
     the argument perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) from
     the permission set referred to by the argument permset_d.  An
     attempt to delete a permission that is not contained in the
     permission set is not considered an error.

     Any existing descriptors that refer to permset_d continue to refer
     to that permission set.

Возвращаемое значение (Return value)

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

Ошибки (Error)

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

     [EINVAL]           The argument permset_d is not a valid descriptor
                        for a permission set within an ACL entry.

                        The argument perm does not contain a valid
                        acl_perm_t value.
