musl/src/thread/pthread_mutex_getprioceiling.c, branch rs-1.0 musl - an implementation of the standard library for Linux-based systems add stub versions of some missing optional pthread interfaces 2012-11-17T23:42:16+00:00 Rich Felker dalias@aerifal.cx 2012-11-17T23:42:16+00:00 5c6443ac42ba00ad3a0b4e98db4cc8f45596ca93 priority inheritance is not yet supported, and priority protection probably will not be supported ever unless there's serious demand for it (it's a fairly heavy-weight feature). per-thread cpu clocks would be nice to have, but to my knowledge linux is still not capable of supporting them. glibc fakes them by using the _process_ cpu-time clock and subtracting the thread creation time, which gives seriously incorrect semantics (worse than not supporting the feature at all), so until there's a way to do it right, it will remain as a stub that always fails.
