现在，让我们看看如何使用这个函数来取消线程。
示例
#include #include #include #include int count = 0;pthread_t sample_thread;void* thread_one_func(void* p) { while (1) { printf("This is thread 1"); sleep(1); // wait for 1 seconds count++; if (count == 5) { //if the counter is 5, then request to cancel thread two and exit from current thread pthread_cancel(sample_thread); pthread_exit(NULL); } }}void* thread_two_func(void* p) { sample_thread = pthread_self(); //store the id of thread 2 while (1) { printf("This is thread 2
"); sleep(2); // wit for 2 seconds }}main() { pthread_t t1, t2; //create two threads pthread_create(&t1, NULL, thread_one_func, NULL); pthread_create(&t2, NULL, thread_two_func, NULL); //wait for completing threads pthread_join(t1, NULL); pthread_join(t2, NULL);}
