Description

The AcxCircuitAddElements function adds elements to an ACXCIRCUIT.

Parameters

Circuit

An existing ACXCIRCUIT object. For more information about ACX objects, see Summary of ACX Objects.

Elements

One or more ACXELEMENT objects that will be added to the circuit.

ElementsCount

The number of elements that will be added to the circuit. This is a one based count.

Return value

Returns STATUS_SUCCESS if the call was successful. Otherwise, it returns an appropriate error code. For more information, see Using NTSTATUS Values.

Remarks

The driver can only add elements to a circuit before the circuit is added to the device. The driver cannot change the circuit's elements at run time.

Example

Example usage is shown below.

    //
    // Add a second element.
    //
    ACX_ELEMENT_CONFIG_INIT(&elementCfg);
    WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE(&attributes, CODEC_ELEMENT_CONTEXT);
    attributes.ParentObject = circuit;

    status = AcxElementCreate(circuit, &attributes, &elementCfg, &elements[1]);

    //
    // Add the elements to the circuit.
    //
    status = AcxCircuitAddElements(circuit, elements, SIZEOF_ARRAY(elements));
