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.
