pthreads does not use errno to return status. It uses the value
directly returned from the routine. Check that value instead of errno.
Darwin's pthreads implementation does not support the optional "Thread
Process-Shared Synchronization" functionality, so calling
pthread_mutexattr_setpshared() with the PTHREAD_PROCESS_SHARED
attribute will return EINVAL.
