3.1.5.2.3 Receiving a CPMGetQueryStatusIn Request

  • Article

When the server receives a CPMGetQueryStatusIn message request from a client, the server MUST do the following:

  1.  Search the ConnectedClientsIdentifiers list for the HANDLE of the named pipe over which the server has received the CPMGetQueryStatusIn message. If it is not present, the server MUST report a STATUS_INVALID_PARAMETER (0xC000000D) error.

  2.  Call the ClientQueryHasCursorHandle abstract interface to the GSS with the HANDLE of the named pipe over which the server has received the CPMGetQueryStatusIn message as its QueryIdentifier argument and with the _hCursor handle as its CursorHandle argument. <26>

  3.   Call the GetQueryStatus abstract interface to the GSS. Use the HANDLE of the named pipe over which the server has received the CPMGetQueryStatusIn message as its QueryIdentifier argument. Prepare a CPMGetQueryStatusOut message, using the QueryStatus output for the _QStatus field. If the Error output is not 0, then report the error.

  4. Respond to the client with the CPMGetQueryStatusOut message.

  5. Report any errors encountered during message preparation or during any abstract interface call to the GSS. Errors that are specific to this request:

    • E_OUTOFMEMORY: generated by any resource allocation failure on the server or service side.

    • STATUS_INVALID_PARAMETER: generated when any of the parameters passed in by the client is invalid. Invalid parameters are those that do not obey the corresponding data structure layout as defined for their types in this document.

    Any other error code can be returned, but it will be treated as informative only.
