The arguments passed to the call must
be pointers to sockaddr_in or
sockaddr_in6 socket address
structures, with either AF_INET or
AF_INET6 as family.
The rtp_open API fails, returning a
negative error value, when the socket
address structures passed belong to
different families.
The library dumps core when
rtp_open is called, or rtp_open
returns negative error number, such
as RTP_EINVAL.
rtp_open
When this API receives an incorrect
argument, or an already closed RTP
descriptor, rtp_close returns
RTP_EINVAL.
The rtp_close API fails with
RTP_EINVAL.
