linux 定時器

     有些東西雖然簡單，但時間長了 不記錄 再用總會多花時間... 記錄下

    

void AlarmFunc(int signo)
{
    pthread_mutex_lock(&g_mutexLock);
    KALDI_LOG << "the feature of " << g_tempEnrollIvectors.size() << "speaker are written into the file";
    for (size_t i = 0; i < g_tempEnrollIvectors.size(); i++)
    {
        g_ivectorWriter.Write(g_tempEnrollIvectors[i].first, *(g_tempEnrollIvectors[i].second));
    }
    g_tempEnrollIvectors.clear();
    pthread_mutex_unlock(&g_mutexLock);
}
