Routine Description:
This function creates and registers a subdevice consisting of a port
driver, a minport driver and a set of resources bound together. It will
also optionally place a pointer to an interface on the port driver in a
specified location before initializing the port driver. This is done so
that a common ISR can have access to the port driver during
initialization, when the ISR might fire.
Arguments:
DeviceObject - pointer to the driver object
Irp - pointer to the irp object.
Name - name of the miniport. Passes to PcRegisterSubDevice
PortClassId - port class id. Passed to PcNewPort.
MiniportClassId - miniport class id. Passed to PcNewMiniport.
MiniportCreate - pointer to a miniport creation function. If NULL,
PcNewMiniport is used.
UnknownAdapter - pointer to the adapter object.
Used for initializing the port.
ResourceList - pointer to the resource list.
PortInterfaceId - GUID that represents the port interface.
OutPortInterface - pointer to store the port interface
OutPortUnknown - pointer to store the unknown port interface.
Return Value:
NT status code.
