See README.NONPORTABLE for descriptions of these routines. - Ramiro Polla +Robust mutexes are implemented within the PROCESS_PRIVATE scope. Robust +mutexes are mandatory (SUSv3 2008) for implementations that support +PSHARED objects and discretionary for those that don't. We still don't +have PSHARED support but wanted to be source code compatible and they +will hopefully nevertheless be useful for some applications. NOTE that +pthread_mutex_*() functions may return different values for robust +mutexes than they otherwise do in normal usage, e.g. +pthread_mutex_unlock() is required to check ownership for all mutex +types when the mutex is robust, whereas this does not occur for the +"normal" non-robust mutex type. +- Ross Johnson + +pthread_getsequence_np is implemented for source level compatibility +with some other implementations.
