ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS structure (acxcircuit.h)

  • Article

The ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS structure contains pointers to an ACXFACTORYCIRCUIT's Plug and Play and power event callback functions.

Syntax

typedef struct _ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS {
  ULONG                                    Size;
  PFN_ACX_FACTORY_CIRCUIT_PREPARE_HARDWARE EvtAcxFactoryCircuitPrepareHardware;
  PFN_ACX_FACTORY_CIRCUIT_RELEASE_HARDWARE EvtAcxFactoryCircuitReleaseHardware;
  PFN_ACX_FACTORY_CIRCUIT_POWER_UP         EvtAcxFactoryCircuitPowerUp;
  PFN_ACX_FACTORY_CIRCUIT_POWER_DOWN       EvtAcxFactoryCircuitPowerDown;
} ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS, *PACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS;

Members

Size

The size, in bytes, of this structure.

EvtAcxFactoryCircuitPrepareHardware

A pointer to the driver's ACX_FACTORY_CIRCUIT_PREPARE_HARDWARE callback event callback function, or NULL.

EvtAcxFactoryCircuitReleaseHardware

A pointer to the driver's ACX_FACTORY_CIRCUIT_RELEASE_HARDWARE callback event callback function, or NULL.

EvtAcxFactoryCircuitPowerUp

A pointer to the ACX_FACTORY_CIRCUIT_POWER_UP callback event callback function, or NULL.

EvtAcxFactoryCircuitPowerDown

A pointer to the ACX_FACTORY_CIRCUIT_POWER_DOWN callback event callback function, or NULL.

Remarks

The ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS structure is used as input to the AcxFactoryCircuitInitSetAcxCircuitPnpPowerCallbacks method.

Your driver should initialize its ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS structure by calling the ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS_INIT function.

Example

Example usage is shown below.

    //
    // Assign the factory circuit's pnp-power callbacks.
    //
    ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS powerCallbacks;
    ACX_FACTORY_CIRCUIT_PNPPOWER_CALLBACKS_INIT(&powerCallbacks);
    powerCallbacks.EvtAcxFactoryCircuitPowerUp = EvtFactoryCircuitPowerUp;
    powerCallbacks.EvtAcxFactoryCircuitPowerDown = EvtFactoryCircuitPowerDown;
    AcxFactoryCircuitInitSetAcxCircuitPnpPowerCallbacks(factoryInit, &powerCallbacks);
