StreamClassRegisterMinidriver

The StreamClassRegisterMinidriver routine registers a stream minidriver with the stream class driver.

NTSTATUS 
  StreamClassRegisterMinidriver(
    IN PVOID  Argument1,
    IN PVOID  Argument2,
    IN PHW_INITIALIZATION_DATA  HwInitializationData
    );

Parameters

Argument1

Points to the first argument to the minidriver's DriverEntry routine.

Argument2

Points to the second argument to the minidriver's DriverEntry routine.

HwInitializationData

Points to an HW_INITIALIZATION_DATA structure that provides the information the class driver needs to begin initializing the minidriver.

Return Value

Returns STATUS_SUCCESS on success, or the appropriate error code on failure.

Headers

Declared in strmini.h. Include strmini.h.

Comments

A stream minidriver must call StreamClassRegisterMinidriver within its DriverEntry routine. For more information, see DriverEntry for Stream Class Minidrivers.

Most of the information passed in the HW_INITIALIZATION_DATA structure informs the class driver of the minidriver-wide callbacks, and what size buffers to allocate for the minidriver's data structures. The class driver queries the minidriver for additional start-up information through SRB_INITIALIZE_DEVICE and SRB_GET_STREAM_INFO requests to the minidriver's StrMiniReceiveDevicePacket routine (passed as the HwReceivePacket member of HW_INITIALIZATION_DATA).

Once registered, a minidriver can drive any number of adapter instances in a system.
