#include <unistd.h>
void thread_1(){
    while(1)
    {
        printf("in thread_1...\n");
    }
}
void thread_2(void *args){
    while(1)
    {
        printf("in thread_2...\n");
    }
}

int main()
{
    pthread_t tid_1;
    pthread_t tid_2;
    char *pArg = (char *)malloc(1024);
    if ((pthread_create(&tid_1, NULL, thread_1, NULL)) == -1)
    {
        printf("thread_1 create failed!\n");
        return 1;
    }
   /*第二个进程是带有入参的*/
   if ((pthread_create(&tid_2, NULL, thread_2, pArg)) == -1)
    {
        printf("thread_2 create failed!\n");
        return 1;
    }
    if(pthread_join(&tid_1, NULL)){
        printf("error join thread_1\n）；
    }
    if(pthread_join(&tid_2, NULL)){
        printf("error join thread_2\n）；
    }
    /*最后，主进程也要进入休眠状态才行，否则立即退出*/
    while(1)
    {
        sleep(1);
    }
    return 0;
}
