The AcxCircuitInitAllocate function is used to initialize the opaque ACXCIRCUIT_INIT structure that is used by the AcxCircuitCreate function.
Syntax

WDFDEVICE Device
);
Parameters
Device
A WDFDEVICE object (described in Summary of Framework Objects) that is associated with the ACX circuit.
Remarks
The driver is responsible for deleting the ACXCIRCUIT_INIT object using AcxCircuitInitFree if the AcxCircuitCreate is not invoked or returns an error.
Example
Example usage is shown below.
PACXCIRCUIT_INIT circuitInit = NULL;
circuitInit = AcxCircuitInitAllocate(Device);
