| H A D | umtx.h | diff 139427 Thu Dec 30 02:56:17 MST 2004 davidxu Make umtx_wait and umtx_wake more like linux futex does, it is more general than previous. It also lets me implement cancelable point in thread library. Also in theory, umtx_lock and umtx_unlock can be implemented by using umtx_wait and umtx_wake, all atomic operations can be done in userland without kernel's casuptr() function. |
