The AcxCircuitInitAssignName function assigns a friendly name for the ACXCIRCUIT.

Syntax

NTSTATUS AcxCircuitInitAssignName(
  PACXCIRCUIT_INIT CircuitInit,
  PCUNICODE_STRING CircuitName
);

Parameters

CircuitInit

The ACXCIRCUIT_INIT structure that defines the circuit initialization. ACXCIRCUIT_INIT is an opaque object used for circuit initialization. Use AcxCircuitInitAllocate to initialize the ACXCIRCUIT_INIT structure.

CircuitName

A unicode string with the circuit name, such as Microphone0.

Remarks

The CircuitName string must match the INF string that identifies the audio interface.

Example

Example usage is shown below.

    // Circuit Name
    DECLARE_CONST_UNICODE_STRING(circuitName, L"Microphone0");

    //
    // Add circuit identifiers.
    //
    AcxCircuitInitSetComponentId(CircuitInit, &COMPONENT_GUID);

    AcxCircuitInitAssignName(CircuitInit, &circuitName);
