C++ (Cpp) NktNtFreeVirtualMemory Examples

Example #1

File: ProcessEntry.cpp Project: 0xra/Deviare-InProc

CProcessesHandles::CEntry::CMemBlock::~CMemBlock()
{
  SIZE_T nSize;

  if (lpBaseAddress != NULL && nFreeCount >= (65536 / nSlotSize))
  {
    nSize = 0;
    NktNtFreeVirtualMemory(hProc, (PVOID*)&lpBaseAddress, &nSize, MEM_RELEASE);
  }
  if (lpFreeEntries != NULL)
    NktHookLibHelpers::MemFree(lpFreeEntries);
  return;
}
