Linux/POSIX equivalent for Win32's CreateEvent, SetEvent, WaitForSingleObject

Question

I have written a small class for synchronizing threads of both Linux (actually Android) and Windows.

Here is the Win32 implementation of my interface :

The pthreads equivalent of your code is:

class SyncObjectPosix
{
private:

    bool signalled;
    pthread_mutex_t mutex;
    pthread_cond_t cond;

public:

    SyncObjectPosix()
    {
        signalled = false;
        pthread_mutex_init(&mutex, NULL);
        pthread_cond_init(&cond, NULL);
    }

    ~SyncObjectPosix()
    {
        pthread_mutex_destroy(&mutex);
        pthread_cond_destroy(&cond);
    }

    void WaitForSignal()
    {
        pthread_mutex_lock(&mutex);
        while (!signalled)
        {
            pthread_cond_wait(&cond, &mutex);
        }
        signalled = false;
        pthread_mutex_unlock(&mutex);
    }

    void Signal()
    {
        pthread_mutex_lock(&mutex);
        signalled = true;
        pthread_mutex_unlock(&mutex);
        pthread_cond_signal(&cond);
    }
};
