BOOL GetPTE(PVOID objAddress, HANDLE hMapPhysicalMemory, HANDLE hSection, PTE& pte)
{
DWORD dwPhysMemBuf = (DWORD)hMapPhysicalMemory, dwAddress = (DWORD)objAddress;
LPVOID pNewMapPhy = NULL;
DWORD dwNewAddress = *((LPDWORD)(dwPhysMemBuf + (dwAddress >> 0x16) * 4));
if ((dwNewAddress & 0x000000ff) < 0x01)
{
return FALSE;
}
if ((dwNewAddress & 0x000000ff) < 0x80)
{
pNewMapPhy = MapViewOfFile(hSection,
4,
0,
dwNewAddress & 0xFFFFF000,
0x1000);
dwNewAddress = (dwAddress >> 0x0c) & 0x3ff;

4 * dwNewAddress)) & 0xFFFFF000;
UnmapViewOfFile(pNewMapPhy);

}

{

}

0, dwNewAddress, 0x1000);
if (pNewMapPhy == NULL)
{
long lError = GetLastError();
return FALSE;
}
else
{
memcpy(&pte, (char *)pNewMapPhy + (dwAddress & 0x00000FFF), sizeof(PTE));
}
UnmapViewOfFile(pNewMapPhy);
return TRUE;
} 最后,我加上了一个Pid到程序名的转换函数:ProcessPidToName。具体程序思路依照ilsy的文章,实现可以参见我的源码。
