WdfPdoInitAddCompatibleID function

Description

[Applies to KMDF only]

The WdfPdoInitAddCompatibleID method adds a compatible ID to the list of compatible IDs for a child device.

Parameters

DeviceInit [in]

A pointer to a WDFDEVICE_INIT structure.

CompatibleID [in]

A pointer to a UNICODE_STRING structure that contains a compatible ID string. The driver can allocate the string's buffer from paged pool.

Return value

If the operation succeeds, the method returns STATUS_SUCCESS. Additional return values include:

Return code Description
STATUS_INVALID_DEVICE_REQUEST The driver is initializing an FDO instead of a PDO.
STATUS_INSUFFICIENT_RESOURCES The driver could not allocate space to store the compatible ID string.

The method might also return other NTSTATUS values.

Remarks

The driver can add one or more compatible IDs for a device. They should be added in order, from best match to worst match. The framework will deliver the IDs to the PnP manager in the order that they were added. For more information about compatible IDs, see Device Identification Strings and How Setup Selects Drivers.

The driver must call WdfPdoInitAddCompatibleID before calling WdfDeviceCreate. For more information about calling WdfDeviceCreate, see Creating a Framework Device Object.

Examples

The following code example reports a compatible ID value that the Toaster sample driver uses.

DECLARE_CONST_UNICODE_STRING(compatId, L"{B85B7C50-6A01-11d2-B841-00C04FAD5171}\\MsCompatibleToaster\0");

status = WdfPdoInitAddCompatibleID(
                                   DeviceInit,
                                   &compatId
                                   );
