我用c++实现了一个线程类。代码如下。 我初始化了两个对象，希望它会启动两个线程(我使用 pthread_self() 来查看线程 ID)。 但是结果显示主线程旁边只有一个线程。 我有点糊涂了……
class Thread {
public:
int mask;
pthread_t thread;
Thread( int );
void start();
static void * EntryPoint (void *);
void Run();
};
Thread::Thread( int a) {
mask =a;
}
void Thread::Run() {
cout<<"thread begin to run" <<endl;
cout <<" Thread Id is: "<< pthread_self() << endl; // the same thread Id.
}
void * Thread::EntryPoint(void * pthis) {
cout << "entry" <<endl;
Thread *pt = (Thread *) pthis;
pt->Run();
}
void Thread::start() {
pthread_create(&thread, NULL, EntryPoint, (void *)ThreadId );
pthread_join(thread, NULL);
}
int main() {
int input_array[8]={3,1,2,5,6,8,7,4};
Thread t1(1);
Thread t2(2);
t1.start();
t2.start()
}
