The acl_strip() function removes all ACLs from a file and replaces them with a trivial ACL based on the mode argument. After replacing the ACL, the owner and group of the file are set to the values specified by the uid and gid arguments.
RETURN VALUES
Upon successful completion, acl_strip() returns 0. Otherwise it returns -1 and sets errno to indicate the error.
