【小小的问题】使用windows api的话可以用pthread.h实现多线程么?

pthread_t t1;
pthread_t t2;
pthread_create(&t1,NULL,tprocess1,NULL);
pthread_create(&t2,NULL,tprocess2,NULL);
pthread_join(t1,NULL);
pthread_join(t2,NULL);
void* tprocess1(void* args){
MessageBox(hButton2,"aaa","提示",MB_OK);
return NULL;
}
void* tprocess2(void* args)
{
MessageBox(hButton2,"aaa","提示",MB_OK); return NULL;
}
一运行就假死...
