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 ~]# ./a.out
