The acl_free_qualifier() function releases the storage space pointed to by the argument tag_qualifier_p. The type of this space is defined by tag_type_d and can be of type, ACL_USER or ACL_GROUP. If it is of type ACL_USER_OBJ, ACL_GROUP_OBJ or ACL_OTHER_OBJ and tag_qualifier_p is NULL a success is returned, otherwise an error is returned.
Upon successful completion, the acl_free_qualifier function returns a value of 0 (zero). Otherwise, a value of -1 is returned and errno is set to indicate the error.
If any of the following conditions occur, the acl_free_qualifier() function sets errno to the corresponding value:
The value of argument tag_type_d is not ACL_USER, ACL_GROUP, ACL_USER_OBJ, ACL_GROUP_OBJ or ACL_OTHER_OBJ
The value of argument tag_type_d is ACL_USER_OBJ, ACL_GROUP_OBJ or ACL_OTHER_OBJ and the value of tag_qualifier_p is not NULL.
