先看例子代码：
void CStudent::menuCallback(CCObject * pSender) {
CStudent *temp = new CStudent("new student", 33);
pthread_mutex_init(&mutex, NULL);//create a mutex
pthread_create(&pidRun, NULL, run, temp); //create a thread
void *run_thread_status = NULL;
pthread_join(pidRun, &run_thread_status); // wait the thread dead,then execute the other threads
pthread_create(&pidGo, NULL, go, 0);
void *thrid_thread_status = NULL;
pthread_join(pidGo, &thrid_thread_status);
pthread_create(&pidThrid, NULL, thrid,NULL);
}
void CStudent::closeCallback(CCObject * pSender) {
}
void *run(void *r) {
CStudent *pStudent = (CStudent *)r;
do
{
CC_BREAK_IF(pStudent == 0);
CCLog("Name: %s, age: %d\n", pStudent->getName(), pStudent->getAge());
while(true) {
pthread_mutex_lock(&mutex);
if(ticket > 20) {
CCLog("Thread Run Sell ticket: %d\n", ticket);
--ticket;
pthread_mutex_unlock(&mutex);
} else {
pthread_mutex_unlock(&mutex);
break;
}
Sleep(1);
}
} while(false);
return NULL;
}
void *go(void *g) {
while(true) {
pthread_mutex_lock(&mutex);
if(ticket > 10 && ticket <= 20) {
CCLog("Go Thread Sell ticket: %d\n", ticket);
--ticket;
pthread_mutex_unlock(&mutex);// the the mutex unsingled
} else {
pthread_mutex_unlock(&mutex);
break;
}
}
Sleep(1);
return NULL;
}
void *thrid(void *t) {
while(true) {
pthread_mutex_lock(&mutex);
if(ticket > 0 && ticket <= 10) {
CCLog("Thrid thread Sell ticket: %d\n", ticket);
--ticket;
pthread_mutex_unlock(&mutex);
} else {
pthread_mutex_unlock(&mutex);
break;
}
}
return NULL;
}
