這篇文章主要介紹了c語(yǔ)言線程終止練習(xí)示例,需要的朋友可以參考下

復(fù)制代碼 代碼如下:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *t1(void *args) {
 return (void *) 0;
}

void *t2(void *args) {
 printf("thread 2 param[args] = %d\n", args);
 pthread_exit((void *) 3);
}

void *t3(void *args) {
 while(1) {
  printf("thread 3 is working\n");
  sleep(1);
 }
}

int main(int argc, char *argv[]) {
 pthread_t thread;
 int err;
 void *status;

 printf("creating thread 1\n");
 err = pthread_create(&thread, NULL, t1, NULL);
 if(err) {
  printf("Can not created thread 1\n");
  exit(-1);
 }
 pthread_join(thread, &status);
 printf("thread 1 exit return code %d\n\n", status);
 

 printf("creating thread 2\n");
 err = pthread_create(&thread, NULL, t2, (void *) 9);
 if(err) {
  printf("Can not created thread 2\n");
  exit(-2);
 }
 pthread_join(thread, &status);
 printf("thread 2 exit return code %d\n\n", status);

  
 printf("creating thread 3\n");
 err = pthread_create(&thread, NULL, t3, NULL);
 if(err) {
  printf("Can not created thread 3\n");
  exit(-3);
 }
 sleep(10);
 pthread_cancel(thread);
 pthread_join(thread, &status);
 printf("thread 3 exit return code %d\n", status);

 return 1;
}
