# librtpmidid
librtpmidid allows to easy adding rtpmidi capabilities to your own free or
commercial project.
The main element is the class rtpmidid::rtppeer, which allows to create peers,
be it clients or servers.
The rtpserver and rtpclient are ready to use client and server as used on rtpmidid
daemon, and do all the required IO, using the
rtpmidid::poller_t.
In all classes it tries to expose al internal state as can be needed for
extending funciontalities.
Also a `rtpmidid::signal_t` is used all around as a subscription service to
events.
## rtpmidid::poller_t
The poller can be reimplemented as needed in other projects, but it may require
recompilation from source code.
## rtpmidid::rtppeer
The flow of a basic rtppeer can be seen on the `test_rtppeer.cpp` file.
It mainly needs to be initialized and connect both the command and control
ends, and then can receive the data buffers, and will call the `send_event` when
needs to send some events, normally due to a `send_midi` call (but can be
`send_ck0`)
## rtpmidid::rtpclient and rtpmidid::rtpserver
These are the network IO handlers. It receives the data as needed to create the
client or server (ip and port) and then it handles all using the
`rtpmidid::poller_t`.
# Tips
## CK0
As client you must follow some extra dance after connecting, as seen at
`rtpclient::connected`:
- Send 6 ck0 in 1500ms intervals
- Send ck every 10 seconds
Failure to do this as a client may result in disconnect from Mac OS and Tobias
Erichsen Rtpmidi for Windows.
## mDNS
At first we had a custom implementation. Bad idea. Better just use avahi.
Also if the computer has several network interfaces it may return several IPS to
connect to. Try them all. The order may be better first ehternet than Wifi, but
just because is listed does not mean it will work.
