多线程编程，被坑了

今天被坑了，以后要长记性了，int main(void),恶心的void，

/* thread.c */

#include
#include
#include

void *thrd_fun1(void *arg)
{
int no=(int)arg;
int delay1;
printf("Thread 1 is starting\n");
while(1)
{
delay1=(int)(rand()*3.0/(RAND_MAX))+1;
sleep(1);
printf("thread 1 delay %d\n",delay1);

}
pthread_exit(NULL);
}

void *thrd_fun2(void *arg)
{
int no=(int)arg;
int delay2;
while(1)
{
delay2=(int)(rand()*10/(RAND_MAX))+1;
printf("thread 2 delay %d\n",delay2);
sleep(delay2);
}
pthread_exit(NULL);
}

int main(void)//最坑人的地方如果不加void会出现卡死现象
{
pthread_t thread[2];
int res=0;
int no=0;
void *thrd_ret;
srand(time(NULL));

res=pthread_create(&thread[0],NULL,thrd_fun1,(void*)no);
if(res!=0)
{
printf("Create thread 1 failed\n");
exit(res);
}
res=pthread_create(&thread[1],NULL,thrd_fun2,(void*)no);
if(res!=0)
{
printf("Create thread 2 failed\n");
exit(res);
}
for(no=0;no<2;no++)
{
res=pthread_join(thread[no],&thrd_ret);
if(!res)
{
printf("Thread %d exit\n",no);
}
else
{
printf("Thread %d exit failed",no);
}
}
return 0;
}
