The CM_Get_Device_Interface_Property_Keys function retrieves an array of device property keys that represent the device properties that are set for a device interface.
CMAPI CONFIGRET CM_Get_Device_Interface_Property_KeysW( LPCWSTR pszDeviceInterface, DEVPROPKEY *PropertyKeyArray, PULONG PropertyKeyCount, ULONG ulFlags );
Pointer to a string that identifies the device interface instance to retrieve the property keys from.
Pointer to a buffer that receives an array of DEVPROPKEY-typed values, where each value is a device property key that represents a device property that is set for the device interface. The pointer is optional and can be NULL
The size, in DEVPROPKEY-typed units, of the PropertyKeyArray buffer. If PropertyKeyArray is set to NULL, *PropertyKeyCount must be set to zero. As output, if PropertyKeyArray is not large enough to hold all the property key data, CM_Get_Device_Interface_Property_Keys returns the count of the keys, in *PropertyKeyCount.
Reserved. Must be set to zero.
If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.
CM_Get_Device_Interface_Property_Keys is part of the Unified Device Property Model.
