SetFilePointer返回什么表示调用失败

[kingstarer]

msdn上面写着失败会返回INVALID_SET_FILE_POINTER

但是我用vc 6.0提示这个宏未定义　网上说是jdk太旧导致的

那在旧版的jdk中　SetFilePointer返回什么表示调用失败呢？　

麻烦哪位大虾有旧版的msdn帮忙查一下，谢谢:)

返回值
你自己看看返回的是哪个吧
#define INVALID_HANDLE_VALUE ((HANDLE)(LONG_PTR)-1)
#define INVALID_FILE_SIZE ((DWORD)0xFFFFFFFF)
#define INVALID_SET_FILE_POINTER ((DWORD)-1)
#define INVALID_FILE_ATTRIBUTES ((DWORD)-1)

[wutaihua]

__int64 myFileSeek (HANDLE hf, __int64 distance, DWORD MoveMethod)
{
   LARGE_INTEGER li;

   li.QuadPart = distance;

   li.LowPart = SetFilePointer (hf, li.LowPart, &li.HighPart, MoveMethod);

   if (li.LowPart == 0xFFFFFFFF && GetLastError() != NO_ERROR)
   {
      li.QuadPart = -1;
   }

   return li.QuadPart;
}

C/C++ code
__int64 myFileSeek (HANDLE hf, __int64 distance, DWORD MoveMethod)
{
LARGE_INTEGER li;

li.QuadPart= distance;

li.LowPart= SetFilePointer (hf, li.LowPart,&li.HighPart, MoveMethod)¡­
