线程的创建等待及退出 代码源码举例

#include<stdio.h>
#include<pthread.h>
void *funcl(void *arg)
{
        printf("t1: %ld thread is create\n",(unsigned long) pthread_self());//pthread_self()为获取线程ID号
        printf("t1:param is %d\n",*((int *)arg));//打印主进程给的参数
}
int main()
{
        int ret;
        int param = 100;
        pthread_t t1;
        ret = pthread_create(&t1, NULL, funcl,(void *)&param);//创建funcl线程，传参并 将返回值给ret
        if(ret == 0){
                printf("main:create t1 success\n");//说明创建成功
        }
        printf("main: %ld\n",(unsigned long)pthread_self());//获取线程ID号
        while(1);//为了等待t1线程执行，不然没等运行，主进程就结束了
        return 0;
}
