## Detailed Description

A UDP/IPv4 socket class targeted at RTP stacks.

This class provides a flat interface that includes all the services required by an RTP stack.

It can be used in two ways:

To instantiate the DualSocket template, which will be used to instantiate an RTP stack template (such as **TRTPSessionBase**).

To directly instantiate an RTP stack template (such as **TRTPSessionBase**).

This class offers an example of the interface that other classes should provide in order to specialize the ccRTP stack for different underlying protocols.
