線程分離的作用：當主線程與新線程無關時，主線程無需等待新線程的結束。

1、進程屬性初始化

pthread_attr_t pth_attr;?
pthread_attr_init(&pth_attr);
2、進程分離屬性設置。

pthread_attr_setdetachstate(&pth_attr,PTHREAD_CREATE_DETACHED);

3、進程創建。

4、進程屬性資源回收。

pthread_attr_destroy(&pth_attr);

#include<stdio.h> #include<string.h> #include<unistd.h> #include<stdlib.h> #include<pthread.h>void *thread_func(void *arg); #define handle_error(msg) \do { perror(msg); exit(EXIT_FAILURE);} while(0) char message[] = "hello Ruanchao!"; int finish=0; int main() {int res;pthread_t thread;pthread_attr_t pth_attr;res = pthread_attr_init(&pth_attr);if (res != 0) handle_error("pthread initial is failed!");res = pthread_attr_setdetachstate(&pth_attr,PTHREAD_CREATE_DETACHED);if(res != 0)handle_error("pthread set attr failed!");res = pthread_create(&thread,&pth_attr,thread_func,(void *)message);if(res != 0)handle_error("thread creation is failed!");(void)pthread_attr_destroy(&pth_attr);while(!finish) {printf("Waiting for thread to end!\n");sleep(1);}printf("thread were finished!\n");exit("EXIT_FAILURE"); } void *thread_func(void *arg){printf("thread_func is running,argument is %s\n",(char *)arg);sleep(5);finish = 1;pthread_exit(NULL); }
