TdiDispatchInternalDeviceControl
TDI_STATUS
TdiDispatchInternalDeviceControl (
IN PDEVICE_OBJECT DeviceObject,
IN PIRP Irp
);
TdiDispatchInternalDeviceControl is a TDI driver function that provides TDI driver control for kernel-mode client requests other than those for opening and closing objects. When preparing a request, the client first issues a request message and then either calls a library build macro to format an IRP or uses an IRP passed in from a higher network layer. It places the request message in the minor function code member of the IRP and uses IRP_MJ_INTERNAL_DEVICE_CONTROL as the major function code. When the IRP is ready, the client calls IoCallDriver to deliver the request to TdiDispatchInternalDeviceControl. TdiDispatchInternalDeviceControl then forwards the client request to the appropriate internal driver function for processing.
