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.

//
// Factory Name.
//
DECLARE_CONST_UNICODE_STRING(s_FactoryName, L"Render");
    
    //
    // Get a FactoryCircuitInit structure.
    //
    factoryInit = AcxFactoryCircuitInitAllocate(Device);

    //
    // Add factory identifiers.
    //
    AcxFactoryCircuitInitSetComponentId(factoryInit, &KSCATEGORY_APXCIRCUITFACTORY);
    AcxFactoryCircuitInitAssignCategories(factoryInit, &KSCATEGORY_APXCIRCUITFACTORY, 1);
    AcxFactoryCircuitInitAssignName(factoryInit, &s_FactoryName);
