|ACL_DELETE_PERM(3)||Library Functions Manual||ACL_DELETE_PERM(3)|
delete a permission from an ACL permission set
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.
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.
acl_delete_perm() function returns
-1and sets errno to the corresponding value:
- 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.
