* Helper class for several RTPTransmitter instances, to be able to cancel a

*
* This is a helper class for several RTPTransmitter instances. Typically a
* call to 'select' (or 'poll' or 'WSAPoll', depending on the platform) is used
* to wait for incoming data for a certain time. To be able to cancel this wait
* from another thread, this class provides a socket descriptor that's compatible
* with e.g. the 'select' call, and to which data can be sent using
* RTPAbortDescriptors::SendAbortSignal. If the descriptor is included in the
* 'select' call, the function will detect incoming data and the function stops
* waiting for incoming data.
*
* The class can be useful in case you'd like to create an implementation which
* uses a single poll thread for several RTPSession and RTPTransmitter instances.
* This idea is further illustrated in `example8.cpp`.

/** A TCP transmission component.

* This class inherits the RTPTransmitter interface and implements a transmission component
* which uses TCP to send and receive RTP and RTCP data. The component's parameters
* are described by the class RTPTCPTransmissionParams. The functions which have an RTPAddress
* argument require an argument of RTPTCPAddress. The RTPTransmitter::GetTransmissionInfo member function
* returns an instance of type RTPTCPTransmissionInfo.
*
* After this transmission component was created, no data will actually be sent or received
* yet. You can specify over which TCP connections (which must be established first) data
* should be transmitted by using the RTPTransmitter::AddDestination member function. This
* takes an argument of type RTPTCPAddress, with which relevant the socket descriptor can
* be passed to the transmitter.
*
* These sockets will also be used to check for incoming RTP or RTCP data. The RTPTCPAddress
* instance that's associated with a received packet, will contain the socket descriptor
* on which the data was received. This descriptor can be obtained using RTPTCPAddress::GetSocket.
*
* To get notified of an error when sending over or receiving from a socket, override the
* RTPTCPTransmitter::OnSendError and RTPTCPTransmitter::OnReceiveError member functions.
