unsigned __stdcall func1( void* b )
 {
      int *p = (int*)b;
      printf("%d", *p );
      return 1;
 }

void func2()
{
     int n = 100;
     int *p = &n;
     _beginthreadex( NULL, 0, &func1, &n, 0, NULL );
}

 

int main()

{

    func2();

    return 0;

}

 

func2中p与func1中b的值一样，输出结果不为100。原因？自己google一下～
