linux pthread多线程编程模板
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; }
