Module Name:

    Process.hxx

Abstract:

    Process objects represent local clients and servers.  These
    objects live as context handles.

    There are relativly few of these objects in the universe.

Class Description:

    An instance of this class is created for each process
    using the OR as either a client or server.

    The process object is referenced by server OXIDs and has
    one implicit reference by the actual process (which is
    dereferenced during the context rundown).  Instances of
    these objects are managed by the RPC runtime as context
    handles.

Members:

    _pToken - A pointer to the CToken instance of the process.

    _csCallbackLock - use to serialize callback to LazyUseProtseq

    _hProcess - An RPC binding handle back to the process.

    _pdsaLocalBindings - The string bindings of the process, including
        local only protseqs

    _pdsaRemoteBindings - A subset of _pdsaLocalBindings not containing
        any local-only protseqs

    _blistOxids - A CBList containing pointers to the CServerOxid's
        owned by this process, if any.

    _blistOids - A CBList of pointers to CClientOid's which this
        process is using and referencing, if any.

    _blistClasses - A CBList of registration handles for classes that
        a server process has registered.
