An application initiates a session for data transport using rtp_open. It may optionally
set control options for the session using the rtp_ioctl interface. The control options
set the addresses of the participating members for the session using the
RTP_SSENDTOADDRLST option through rtp_ioctl.
To send a packet containing media data to all the participating members of a session
using rtp_send, the application creates a media packet in the format prescribed by
the RTP packet structure, rtp_pkt_t.
The application can send an RTP packet, stored in the RTP packet structure, using
rtp_send.
