New services can be provided by the extension layer through the standard stream driver IOControl mechanism. Applications can access these new services through the new IOCTL calls.

The following illustrates how to add new IOCTL functions.

int iRes = DeviceIoControl (
   hFile, LAYER_IOCTL_SERVICE_1, 
   &p, sizeof(p), NULL, 0, NULL, NULL
);
