本文导语: #include #include #include #include struct chuan { int h; char a; }; void *myThread1(struct chuan *q1) { printf("This is the 1st pthread,created by zieckey.n"); printf("The struct is %dn",q1.h); ...

struct chuan
{
int h;
char a;
};
void *myThread1(struct chuan *q1)
{
printf("This is the 1st pthread,created by zieckey.n");
printf("The struct is %dn",q1.h);
sleep(1);//Let this thread to sleep 1 second,and then continue to run
}
int main()
{
int i=0, ret=0;
pthread_t id1;
struct chuan qq={1,"d"};
ret = pthread_create(&id1, NULL, (void*)myThread1,&qq );
if (ret)
{
printf("Create pthread error!n");
return 1;
}
pthread_join(id1, NULL);
return 0;
}
提示出错：request for member ‘h’ in something not a structure or union
