[Applies to KMDF and UMDF]
The WDF_USB_CONTINUOUS_READER_CONFIG_INIT function initializes a WDF_USB_CONTINUOUS_READER_CONFIG structure.
Config [out]A pointer to a WDF_USB_CONTINUOUS_READER_CONFIG structure.
EvtUsbTargetPipeReadComplete [in]A pointer to the driver's EvtUsbTargetPipeReadComplete callback function.
EvtUsbTargetPipeReadCompleteContext [in]An untyped pointer to driver-defined context information that the framework passes to the driver's EvtUsbTargetPipeReadComplete callback function.
TransferLength [in]The maximum length, in bytes, of data that can be received from the device.
The WDF_USB_CONTINUOUS_READER_CONFIG_INIT function zeros the specified WDF_USB_CONTINUOUS_READER_CONFIG structure and sets the structure's Size member. It also sets the structure's EvtUsbTargetPipeReadComplete, EvtUsbTargetPipeReadCompleteContext, and TransferLength members to the specified values.
Note that WDF_USB_CONTINUOUS_READER_CONFIG_INIT does not set the structure's EvtUsbTargetPipeReadersFailed member.
After calling WDF_USB_CONTINUOUS_READER_CONFIG_INIT, the driver can optionally add a EvtUsbTargetPipeReadersFailed pointer to the WDF_USB_CONTINUOUS_READER_CONFIG structure.
For a code example that uses WDF_USB_CONTINUOUS_READER_CONFIG_INIT, see WdfUsbTargetPipeConfigContinuousReader.
