我试图在Linux中实现非常简单的Windows事件.仅适用于我的场景 - 3个线程,1个主线程和2个辅助线程.每个辅助线程通过SetEvent引发1个事件,主线程等待它.例:

int main()
{
    void* Events[2];
    Events[0] = CreateEvent();
    Events[1] = CreateEvent();

    pthread_start(Thread, Events[0]);
    pthread_start(Thread, Events[1]);

    WaitForMultipleObjects(2, Events, 30000) // 30 seconds timeout

    return 0;
}

int* thread(void* Event)
{
    // Do something
    SetEvent(Event);
    // Do something
}

因此,为了实现它,我使用条件变量.但我的问题是 - 这是正确的方法吗？或者我做错了什么？我的实施:

// Actually, this function return pointer to struct with mutex and cond
// here i just simplified example
void* CreateEvent(mutex, condition)
{
    pthread_mutex_init(mutex, NULL);
    pthread_cond_init(condition, NULL);
}

bool SetEvent (mutex, condition)
{
    pthread_mutex_lock(mutex);
    pthread_cond_signal(condition);
    pthread_mutex_unlock(mutex);
}
