我有一个关于pthread_kill()行为的问题.

这是我正在尝试的一个小代码:

void my_handler1(int sig)
{
    printf("my_handle1: Got signal %d, tid: %lu\n",sig,pthread_self());
    //exit(0);
}

void *thread_func1(void *arg)
{
    struct sigaction my_action;
    my_action.sa_handler = my_handler1;
    my_action.sa_flags = SA_RESTART;
    sigaction(SIGUSR1, &my_action, NULL);
    printf("thread_func1 exit\n");
}


void *thread_func2(void *arg)
{
    int s;
    s = pthread_kill(tid1_g,SIGUSR1);
    if(s)
            handle_error(s,"tfunc2: pthread_kill");

    printf("thread_func2 exit\n");
}


int main()
{
    int s = 0;
    pthread_t tid1;

    s = pthread_create(&tid1,NULL,thread_func1,NULL);
    if(s)
            handle_error(s,"pthread_create1");

    tid1_g = tid1;
    printf("tid1: %lu\n",tid1);
    s = pthread_join(tid1,NULL);
    if(s)
            handle_error(s, "pthread_join");

    printf("After join tid1\n");

    pthread_t tid3;
    s = …
