WDU_GetDeviceRegistryProperty()

DWORD DLLCALLCONV WDU_GetDeviceRegistryProperty	(	_In_ WDU_DEVICE_HANDLE	hDevice,
		_Outptr_ PVOID	pBuffer,
		_Inout_ PDWORD	pdwSize,
		_In_ WD_DEVICE_REGISTRY_PROPERTY	property
	)

Gets the specified registry property of a given device.

Parameters

[in]	hDevice	A unique identifier of the device/interface.
[out]	pBuffer	Pointer to a user allocated buffer to be filled with the requested registry property. The function will fill the buffer only if the buffer size, as indicated in the input value of the pdwSize parameter, is sufficient - i.e >= the property's size, as returned via pdwSize. pBuffer can be set to NULL when using the function only to retrieve the size of the registry property (see pdwSize).
[in,out]	pdwSize	As input, points to a value indicating the size of the user-supplied buffer (pBuffer); if pBuffer is set to NULL, the input value of this parameter is ignored. As output, points to a value indicating the required buffer size for storing the registry property.
[in]	property	The ID of the registry property to be retrieved - see the WD_DEVICE_REGISTRY_PROPERTY enumeration in windrvr.h. Note: String registry properties are in WCHAR format.

Returns

WinDriver Error Code.

Note

When the size of the provided user buffer (pBuffer) - *pdwSize (input) is not sufficient to hold the requested registry property, the function returns WD_INVALID_PARAMETER.
