void clean_fun1(void * arg)

{

printf("this is clean fun1\n");

}

//这里要注意,如果将sleep(100);换成while(1);的话,程序会一直暂停.push和pop要成对出现.

//因为while(1);运行的太快,线程不接受cancel信号

//while(1);

pthread_cleanup_pop(0);

return NULL;

}

int main()

pthread_t tid1;

int err;

err=pthread_create(&tid1,NULL,thread_fun,NULL);

exit(0);

}

sleep(3);

//printf("test\n");

err=pthread_cancel(tid1);

if(err!=0)

{

perror("cancel error:");

exit(0);

}

err=pthread_join(tid1,NULL);

if(err!=0)
