CM_Get_Device_Interface_PropertyW function

-description

The CM_Get_Device_Interface_Property function retrieves a device property that is set for a device interface.

-parameters

-param pszDeviceInterface [in]

Pointer to a string that identifies the device interface instance to retrieve the property from.

-param PropertyKey [in]

Pointer to a DEVPROPKEY structure that represents the device interface property key of the device interface property to retrieve.

-param PropertyType [out]

Pointer to a DEVPROPTYPE-typed variable that receives the property-data-type identifier of the requested device interface property. The property-data-type identifier is a bitwise OR between a base-data-type identifier and, if the base-data type is modified, a property-data-type modifier.

-param PropertyBuffer [out]

A pointer to a buffer that receives the requested device interface property. CM_Get_Device_Interface_Property retrieves the requested property only if the buffer is large enough to hold all the property value data. The pointer can be NULL.

-param PropertyBufferSize [in, out]

The size, in bytes, of the PropertyBuffer buffer. If PropertyBuffer is set to NULL, *PropertyBufferSize must be set to zero. As output, if the buffer is not large enough to hold all the property value data, CM_Get_Device_Interface_Property returns the size of the data, in bytes, in *PropertyBufferSize.

-param ulFlags [in]

Reserved. Must be set to zero.

-returns

If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.

-remarks

CM_Get_Device_Interface_Property is part of the Unified Device Property Model.
