怎么用WINIO去读FFFFFFFF这个地址？
怎么用WINIO去读FFFFFFFF这个地址？ 贴一个WINIO自带的例子：#include <windows.h>
#include <stdio.h>
#include "winio.h"
void main()
{
DWORD dwPortVal;
DWORD dwMemVal;
bool bResult;
HANDLE hPhysicalMemory;
PBYTE pbLinAddr;
// Call InitializeWinIo to initialize the WinIo library.
bResult = InitializeWinIo();
if (bResult)
{
// Under Windows NT/2000/XP, after calling InitializeWinIo,
// you can call _inp/_outp instead of using GetPortVal/SetPortVal
GetPortVal(0x378, &dwPortVal, 4);
SetPortVal(0x378, 10, 4);
// Map physical addresses 0xA0000 - 0xAFFFF into the linear address space
// of the application. The value returned from the call to MapPhysToLin is
// a linear address corresponding to physical address 0xA0000. In case of
// an error, the return value is NULL.
pbLinAddr = MapPhysToLin((PBYTE)0xA0000, 65536, &hPhysicalMemory);
if (pbLinAddr)
{
// Now we can use pbLinAddr to access physical address 0xA0000
*pbLinAddr = 10;
// When you're done with pbLinAddr, call UnmapPhysicalMemory
UnmapPhysicalMemory(hPhysicalMemory, pbLinAddr);
}
// Instead of using MapPhysToLin, we can use GetPhysLong/SetPhysLong
GetPhysLong((PBYTE)0xA0000, &dwMemVal);
SetPhysLong((PBYTE)0xA0000, 10);
// When you're done using WinIo, call ShutdownWinIo
ShutdownWinIo();
}
else
{
printf("Error during initialization of WinIo.\n");
exit(1);
}
} 楼上的有试过吗？楼主所说的 地址超过2G了哦 我目前也是2G之后就不行了 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。 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。:lol 我路过,,我是菜鸟, 原帖由 happybasic 于 2008-12-13 17:07 发表 http://www.ufoit.com/bbs/images/common/back.gif

请问现在这个修改过的winIo库还有吗？好像删除了 已经找到了，感谢各位~ pStartPhysAddress.QuadPart = (ULONGLONG)pPhysAddress &....... 也在为读取2G以上的地址所困扰，谢谢
所说的附件呢？
