示例：
pthread_attr_t attr;
pthread_t threadId;
int returnVal;

	returnVal = pthread_attr_init(&attr);
	assert(!returnVal);

	returnVal = pthread_attr_setdetachstate(&attr,PTHREAD_CREATE_DETACHED);
	assert(!returnVal);

	int threadError = 0;
	threadError = pthread_create(&threadId, &attr, &threadWorldStep, NULL);

	returnVal = pthread_attr_destroy(&attr);
	assert(!returnVal);

	if (threadError != 0)
		CCLog("create thread error");
