Routine Description :

    Marshals a usr_marshall object.

    The format string layout is as follows:

        FC_USER_MARSHAL
        flags & alignment<1>
        quadruple index<2>
        memory size<2>
        wire size<2>
        type offset<2>

    The wire layout description is at the type offset.

Arguments :

    pStubMsg    - Pointer to the stub message.
    pMemory     - Pointer to the usr_marshall object to marshall.
    pFormat     - Object's format string description.

Return :

    None.
