Linux中以PTHREAD_CREATE_DETACHED属性创建线程
在线程创建时将其属性设为分离状态(detached),也可在线程创建后将其属性设为分离的(detached)。
这里使用在创建时指定线程为PTHREAD_CREATE_DETACHED属性。
一、实例
#include <dirent.h> #include <pthread.h> #include <errno.h> #include <signal.h> #include <time.h> void* thread1(void *arg) { while (1) { usleep(100 * 1000); printf("thread1 running...!\n"); } printf("Leave thread1!\n"); return NULL; } int main(int argc, char** argv) { pthread_t tid; pthread_attr_t attr; pthread_attr_init(&attr); pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED); // 设置分离属性 pthread_create(&tid, &attr, (void*)thread1, NULL); pthread_attr_destroy(&attr); sleep(1); printf("Leave main thread!\n"); return 0; }
程序输出:
[root@robot ~]# gcc thread_detach.c -lpthread
[root@robot ~]# ./a.out
