Linux Access Control Lists library (libacl, -lacl).


SYNOPSIS

     int
     acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm)


DESCRIPTION

     The acl_delete_perm() function deletes the permission contained in the
     argument perm 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.


RETURN VALUE

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


ERRORS

     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 per­
                   mission set within an ACL entry.

                   The argument perm does not contain a valid acl_perm_t val­
                   ue.


STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
