1.1.2.4.15 DRV_G3_MACRT_ExceptionCallbackRegister Function

void DRV_G3_MACRT_ExceptionCallbackRegister (
    const DRV_HANDLE handle,
    const DRV_G3_MACRT_EXCEPTION_CALLBACK callback
);

Allows a client to set an exception event handling function for the driver to call back when some error occurs through PLC transceiver communication.

This function allows a client to register a PLC exception event handling function for the driver to call back when a communication SPI error occurs.

The event handler should be set before using the PLC transceiver in order to capture error events. The callback once set, persists until the client closes the driver or sets another callback (which could be a NULL pointer to indicate no callback).

DRV_G3_MACRT_Open must have been called to obtain a valid opened device handle.

None.

void APP_PLC_Exception_callback(DRV_G3_MACRT_EXCEPTION_OBJ *exceptionObj)
{
    // Exception handling here.
}

// myAppObj is an application specific state data object.
MY_APP_OBJ myAppObj;

// Client registers an exception callback with driver. This is done once
// 'myHandle', returned from DRV_G3_MACRT_Open previously called
DRV_G3_MACRT_ExceptionCallbackRegister( myAppObj.myHandle, APP_PLC_Exception_callback );

None.
