Hi!Isn't this thread unsafe? struct event_t { SLONG event_count; int pid; pthread_mutex_t event_mutex[1]; pthread_cond_t event_cond[1]; }; int SharedMemoryBase::eventPost(event_t* event) { ... ++event->event_count; ... } Should not event_count use a std::atomic? Or is SharedMemoryBase::eventPost expected to not be thread safe to be called concurrently?
It's always called with shared memory mutex taken, i.e. no concurrency problems.
