AcxCircuitInitSetAcxCircuitPnpPowerCallbacks function (acxcircuit.h)
The AcxCircuitInitSetAcxCircuitPnpPowerCallbacks function sets the driver's PNP callbacks for the ACXCIRCUIT.
Syntax
void AcxCircuitInitSetAcxCircuitPnpPowerCallbacks(
PACXCIRCUIT_INIT CircuitInit,
PACX_CIRCUIT_PNPPOWER_CALLBACKS EvtPnpPowerCallbacks
);
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.
EvtPnpPowerCallbacks
An ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS PnP power callbacks structure that defines the callbacks.
Return value
None
Remarks
Before calling AcxCircuitInitSetAcxCircuitPnpPowerCallbacks, your driver should initialize its ACX_CIRCUIT_PNPPOWER_CALLBACKS structure by calling ACX_CIRCUIT_PNPPOWER_CALLBACKS_INIT. The ACX_CIRCUIT_PNPPOWER_CALLBACKS structure is used as input to the AcxCircuitInitSetAcxCircuitPnpPowerCallbacks method.
Example
Example usage is shown below.
//
// Assign the circuit's pnp-power callbacks.
//
ACX_CIRCUIT_PNPPOWER_CALLBACKS_INIT(&powerCallbacks);
powerCallbacks.EvtAcxCircuitPowerUp = CodecR_EvtCircuitPowerUp;
powerCallbacks.EvtAcxCircuitPowerDown = CodecR_EvtCircuitPowerDown;
AcxCircuitInitSetAcxCircuitPnpPowerCallbacks(circuitInit, &powerCallbacks);
