NAME
volume − volume control for an infrared interface
SYNOPSIS
include "volume.m"; vctl := load Volumectl Volumectl->PATH;
volumectl: fn(ctxt: ref Draw->Context, ch: chan of int, device: string);
DESCRIPTION
Volumectl should be spawned as a separate process from any process that desires volume control via an infrared interface. Ctxt provides volumectl with access to the display, on which it displays a slider widget. The slider automatically disappears after several seconds of inactivity. Volumectl receives input from the infrared controller on channel ch. The values recognized are:
VolUP
increase volume
VolDN
decrease volume
Enter exit
Device is a string used as a prefix to commands to the device; for example "audio out" for audio(3).
