AcxTargetCircuitGetTargetElement function (acxtargets.h)
The AcxTargetCircuitGetTargetElement function, given a valid element index value, will return the associated ACXTARGETELEMENT object.
Syntax
ACXTARGETELEMENT AcxTargetCircuitGetTargetElement(
ACXTARGETCIRCUIT TargetCircuit,
ULONG ElementIndex
);
Parameters
TargetCircuit
An ACXTARGETCIRCUIT handle. For more information about ACX objects, see Summary of ACX Objects.
ElementIndex
A valid element index value.
Return value
Returns a ACXTARGETELEMENT ACX Object that is associated with the specified circuit.
Remarks
Example
// Search the target circuit for a volume element.
// This sample code doesn't support downstream audioengine elements.
//
for (ULONG elementIndex = 0; elementIndex < AcxTargetCircuitGetElementsCount(TargetCircuit); ++elementIndex)
{
ACXTARGETELEMENT targetElement = AcxTargetCircuitGetTargetElement(TargetCircuit, elementIndex);
GUID elementType = AcxTargetElementGetType(targetElement);
if (IsEqualGUID(elementType, KSNODETYPE_VOLUME) &&
circuitCtx->TargetVolumeHandler == nullptr)
{
// Found Volume
circuitCtx->TargetVolumeHandler = targetElement;
}
}
