Linux多线程——异步

Linux线程异步

test.c

#include <pthread.h>
#include <stdlib.h>
#include <stdio.h>
void* thread1Func(void* arg)
{
         printf("childThread1 is running\n");
         pthread_exit((void*)0);

          printf("childThread2 is running\n");
          pthread_exit((void*)0);
}

void* ret_result_thread1;
void* ret_result_thread2;
int main(int argc, char** argv)
{
      printf("main thread is running\n");
      pthread_t thread1,thread2;
      int result;
      if( (result = pthread_create(&thread1,NULL,thread1Func,NULL)) != 0)
      {
             perror("thread1 create failed");
      }

      if( (result = pthread_create(&thread2,NULL,thread2Func,NULL)) != 0)
      {
             perror("thread2 create failed");
      }

       pthread_join(thread1,ret_result_thread1);
       pthread_join(thread2,ret_result_thread2);

       printf("main thread is finished\n");
       return 0;
}

注意：线程的返回结果不能定义为局部变量，否则会报segmentation fault（段错误）
