SND_JACK_SET_KEY(9) Miscellaneous Functions SND_JACK_SET_KEY(9)NAME
snd_jack_set_key - Set a key mapping on a jack
int snd_jack_set_key(struct snd_jack * jack, enum snd_jack_types type, int keytype);
The jack to configure
Jack report type for this key
Input layer key type to be reported
Map a SND_JACK_BTN_ button type to an input layer key, allowing reporting of keys on accessories via the jack abstraction. If no mapping is
provided but keys are enabled in the jack type then BTN_n numeric buttons will be reported.
If jacks are not reporting via the input API this call will have no effect.
Note that this is intended to be use by simple devices with small numbers of keys that can be reported. It is also possible to access the
input device directly - devices with complex input capabilities on accessories should consider doing this rather than using this
This function may only be called prior to registration of the jack.
Zero if successful, or a negative error code on failure.

jack.udp - JACK UDP Transport Client
jack.udp [options] send|recv
OPTIONS -b : Set the ring buffer size in frames (default=4096). -c : Set the client name (default=jack.udp-PID). -n : Set the number of channels,
and therefore the number of JACK ports (default=2). -p : Set the port number (default=57160). -r : The remote host name, for use in send
jack.udp is a UDP audio transport mechansim for JACK. The send mode reads signals from a set of JACK input ports and sends UDP packets to
the indicated port at the indicated host at a rate determined by the local JACK daemon. The recv mode reads incoming packets at the indi-
cated port and writes the incoming data to a set of JACK output ports at a rate that is determined by the local JACK daemon.
This transport mechanism is unreliable. Both send and recv clients will report buffer overflow and underflow occurences, and recv clients
will report dropped and out-of-order packets, and shutdown on channel mismatch packets. In practice this mechanism can be made highly reli-
able over local networks.
jack.udp implements no connection logic, use jack.plumbing(1) instead.
192.0.0.1:~$ jack.udp -r 192.0.0.2 send
192.0.0.2:~$ jack.udp recv
