pthread_create() 创建线程,pthread_join()让线程一直运行下去。

链接时要加上-lpthread选项。

pthread_create中, 第三个参数为线程函数,定义如下:

  void * heartbeat_thread()

  {

    ...

  }

下面是main.c :

#include <pthread.h>

pthread_t thread[MAX_THREAD_NUM];
pthread_mutex_t cache_mutex;
pthread_mutex_t variable_mutex;
pthread_mutex_t time_mutex;
pthread_mutex_t msg_mutex;

void thread_create(void)
{
    int temp;
    memset(thread, 0, sizeof(pthread_t) * MAX_THREAD_NUM);
    if((temp = pthread_create(&thread[0], NULL, heartbeat_thread, NULL)) != 0)
        printf("heartbeat thread create failed\n");
    if((temp = pthread_create(&thread[1], NULL, timesync_thread, NULL)) != 0)
        printf("tiemsync thread create failed\n");
    if((temp = pthread_create(&thread[2], NULL, udpclient_thread, NULL)) != 0)
        printf("udpclient thread create failed\n");
    if((temp = pthread_create(&thread[3], NULL, udpserver_thread, NULL)) != 0)
        printf("udpserver thread create failed\n");
    if((temp = pthread_create(&thread[4], NULL, msgdisplay_thread, NULL)) != 0)
        printf("msgdisplay thread create failed\n");
}

void thread_wait(void)
{
    if(thread[0] !=0)
    {
      pthread_join(thread[0],NULL);
      printf("heartbeat thread finish\n");
    }
    if(thread[1] !=0)
    {
        pthread_join(thread[1],NULL);
        printf("tiemsync thread finish\n");
    }
    if(thread[2] !=0)
    {
        pthread_join(thread[2],NULL);
        printf("udpclient thread finish\n");
    }
    if(thread[3] !=0)
    {
        pthread_join(thread[3],NULL);
        printf("udpserver thread finish\n");
    }
    if(thread[4] !=0)
    {
        pthread_join(thread[4],NULL);
        printf("msgdisplay thread finish\n");
    }
}

int main(void)
{
    pthread_mutex_init(&cache_mutex,NULL);
    pthread_mutex_init(&variable_mutex,NULL);
    pthread_mutex_init(&time_mutex,NULL);
    pthread_mutex_init(&msg_mutex,NULL);
    
    thread_create();
    thread_wait();
    
    pthread_mutex_destroy(&msg_mutex);
    pthread_mutex_destroy(&time_mutex);
    pthread_mutex_destroy(&variable_mutex);
    pthread_mutex_destroy(&cache_mutex);
    return 0;
}
