BOOL VirtualSetAttributes (
    HANDLE hProc,
    LPVOID lpvAddress,
  DWORD cbSize,
  DWORD dwNewFlags,
  DWORD dwMask,
    LPDWORD lpdwOldFlags
);

Parameters

  • hProc
    [in] Handle to a process owning virtual memory whose attributes are to be changed.
  • lpvAddress
    [in] Start address of the virtual memory whose attributes are to be changed.
  • cbSize
    [in] Length, in bytes, of the virtual memory whose attributes are to be changed.
  • dwNewFlags
    [in] Specifies the new value of the bits to be set.
  • dwMask
    [in] Specifies which bits are to be changed.
  • lpdwOldFlags
    [in] If this parameter is not NULL, *lpdwOldFlags will contain the original value of the page entry of the first page upon return.
