AcxFactoryCircuitInitSetOperationCallbacks function (acxcircuit.h)

Artikel
02/22/2024

The AcxFactoryCircuitInitSetOperationCallbacks sets the driver factory operation callbacks for the ACXFACTORYCIRCUIT.

Syntax

void AcxFactoryCircuitInitSetOperationCallbacks(
  PACXFACTORYCIRCUIT_INIT                  FactoryInit,
  PACX_FACTORY_CIRCUIT_OPERATION_CALLBACKS EvtOperationCallbacks
);

Parameters

FactoryInit

An ACXFACTORYCIRCUIT_INIT structure that is used for circuit factory initialization. This is an opaque structure that is used to store ACX Circuit factory initialization information and associate the factory with a WDF device.

Use the AcxFactoryCircuitInitAllocate function to initialize the ACXFACTORYCIRCUIT_INIT structure.

EvtOperationCallbacks

An ACX_FACTORY_CIRCUIT_OPERATION_CALLBACKS structure that identifies the driver callbacks for ACX factory operations.

Return value

None

Remarks

ACX invokes these callbacks to ask the factory to create or remove circuits.

Example

Example usage is shown below.

    //
    // Get a FactoryCircuitInit structure.
    //
    PACXFACTORYCIRCUIT_INIT factoryInit = NULL;
    factoryInit = AcxFactoryCircuitInitAllocate(Device);

    //
    // Add factory identifiers.
    //
    RETURN_NTSTATUS_IF_FAILED(AcxFactoryCircuitInitAssignComponentUri(factoryInit, &dspFactoryUri));
    RETURN_NTSTATUS_IF_FAILED(AcxFactoryCircuitInitAssignName(factoryInit, &dspFactoryName));

    //
    // Assign the circuit's operation-callbacks.
    //
    ACX_FACTORY_CIRCUIT_OPERATION_CALLBACKS operationCallbacks;
    ACX_FACTORY_CIRCUIT_OPERATION_CALLBACKS_INIT(&operationCallbacks);

    operationCallbacks.EvtAcxFactoryCircuitCreateCircuitDevice = Dsp_EvtAcxFactoryCircuitCreateCircuitDevice;
    operationCallbacks.EvtAcxFactoryCircuitCreateCircuit = Dsp_EvtAcxFactoryCircuitCreateCircuit;
    AcxFactoryCircuitInitSetOperationCallbacks(factoryInit, &operationCallbacks);
