怎么用WINIO去读FFFFFFFF这个地址？

贴一个WINIO自带的例子：

  HANDLE hPhysicalMemory;
, v5 f2 g* c: G  PBYTE pbLinAddr;
$ r8 R. z- n3 ]% v( W, r, x9 H
  // Call InitializeWinIo to initialize the WinIo library.
% T( n) }# K  r8 y0 o. Y
( q3 v1 @- W; n3 h# R  bResult = InitializeWinIo();

  if (bResult)
  {
    // Under Windows NT/2000/XP, after calling InitializeWinIo,
0 R) G5 l) e( o( J4 {    // you can call _inp/_outp instead of using GetPortVal/SetPortVal

    GetPortVal(0x378, &dwPortVal, 4);
: ^0 |8 O1 ]5 ]" |
    SetPortVal(0x378, 10, 4);

3 m, x  V4 ^6 z3 f" R1 i* p    // Map physical addresses 0xA0000 - 0xAFFFF into the linear address space
    // of the application. The value returned from the call to MapPhysToLin is

楼上的有试过吗？楼主所说的 地址超过2G了哦

happybasic

我目前也是2G之后就不行了

Alexander

WinIO是有2G的限制，因为2G~4G之间属于系统部分，Microsoft是不会让用户自己乱搞的。

happybasic

此问题已解决，请用附件改过的WinIo库，就可以访问到>2G的memory了

刚收到一位在用我改过的WinIo的网友提醒说我可能在违反license ... 很晕的说，他先下了，再提醒我....

winio早已经不维护了，他自己有bug还不许别人修改吗。

原来的作者误以为_LARGE_INTEGER的QuartPart是个无符号数了。
