Message API functions define handles for the different types of messages. For
example:
 RvSipMsgHandle—defines the handle to a message.
 RvSipViaHeaderHandle—defines the handle to a Via header
object.
 RvSipAddressHandle—defines the handle to an Address
object.
When you construct an object, the Construct() function returns the handle to the
newly created object. Whenever performing an operation on the object, you
must supply the object handle to the function.

The MessageMgr manages the collection of messages and message parts that are
not related to a specific message. It is used to construct stand-alone messages
and message parts. For more information, see Creating a Stand-alone Header
and Creating a New SIP Message.
You can get the MessageMgr handle by calling the
RvSipStackGetMsgMgrHandle() function.
