The QtopiaIpcEnvelope class encapsulates and sends QCop messages.

QCop messages allow applications to communicate with each other by sending messages using QtopiaIpcEnvelope and receiving messages by connecting to a QtopiaChannel.

To send a message, use the following protocol:

    QtopiaIpcEnvelope e(channelname, messagename);
    e << parameter1 << parameter2 << ...;

For messages without parameters, simply use:

    QtopiaIpcEnvelope e(channelname, messagename);

See also QtopiaChannel, QtopiaIpcAdaptor, and QtopiaServiceRequest.
