SpbDeviceInitConfig function (spbcx.h)

Artikel
02/22/2024

The SpbDeviceInitConfig method attaches the SPB framework extension (SpbCx) to the I/O-request chain for a WDFDEVICE (FDO or PDO) object that is to be created.

Syntax

NTSTATUS SpbDeviceInitConfig(
  [in, out] WDFDEVICE_INIT *DeviceInit
);

Parameters

[in, out] DeviceInit

A pointer to the WDFDEVICE_INIT structure that is to be configured.

Return value

SpbDeviceInitConfig returns STATUS_SUCCESS if the call is successful. Possible return values include the following error code.

Return code	Description
STATUS_INSUFFICIENT_RESOURCES	Cannot allocate the required system resources.

Remarks

This method associates the configuration information for SpbCx with the WDFDEVICE_INIT structure for the device object (PDO or FDO) that is to be created. Your driver's EvtDriverDeviceAdd callback routine should call SpbDeviceInitConfig before it calls the WdfDeviceCreate method to create the device object.

Examples

The following code example shows how to use the SpbDeviceInitConfig method to associate the SpbCx framework extension's configuration information with the WDFDEVICE_INIT structure.

//
// FxDeviceInit is a pointer to a WDFDEVICE_INIT structure that comes as a
// parameter for an EvtDriverDeviceAdd handler, or from WdfPdoInitAllocate.
//

status = SpbDeviceInitConfig(FxDeviceInit);

if (!NT_SUCCESS(status))
{
    return status;
}

// 
// Set WDF and SpbCx device-level configuration options.
//

...

//
// Call WdfDeviceCreate
//

status = WdfDeviceCreate(&FxDeviceInit,...);
