Writing a Server MTM

This section explains the initial set up steps to be performed to write a Server MTM. It does not explain the implementation of all Server MTM functionality, however, you can refer the Server MTM example for detailed implementation steps.


Server MTM functions usually start an operation to perform a task asynchronously. The CBaseServerMtm Server MTM class passes its own iStatus member to the operation. Note that there is no base class for server-side operations, as there is on the client side. Server MTMs therefore implement their own operation classes derived directly from CActive. They are, however, usually designed to return progress in a similar way to a client-side operation.


  1. Derive a class from the CBaseServerMtm class.
  2. Register it using the CRegisteredMtmDll parameter.
  3. Create the CActive -based classes for performing the different operations that are required for your Messaging protocol.

Server MTM example

//  CTextServerMtm: The Server-side MTM implementation
CTextServerMtm* CTextServerMtm::NewL(CRegisteredMtmDll& aRegisteredMtmDll, CMsvServerEntry* aInitialEntry)
// Exported factory function
    CTextServerMtm* self=new (ELeave) CTextServerMtm(aRegisteredMtmDll, aInitialEntry);

    return self;

CTextServerMtm::CTextServerMtm(CRegisteredMtmDll& aRegisteredMtmDll, CMsvServerEntry* aInitialEntry)
    :  CBaseServerMtm(aRegisteredMtmDll, aInitialEntry),
