WSMUX(4)                NetBSD Kernel Interfaces Manual               WSMUX(4)


NAME
wsmux -- console keyboard/mouse multiplexor for wscons
SYNOPSIS
wskbd* at ... mux 1 wsbell* at ... mux 1 wsmouse* at ... mux 0 pseudo-device wsmux
DESCRIPTION
The wsmux is a pseudo-device driver that allows several wscons(4) input devices to have their events multiplexed into one stream. The typical usage for this device is to have two multiplexors, one for mouse events and one for keyboard and bell events. All wsmouse(4) devices should direct their events to the mouse mux (normally 0) and all keyboard devices, except the console, should direct their events to the keyboard mux (normally 1). A device will send its events to the mux indicated by the mux locator. If none is given the device will not use a multiplexor. The keyboard multiplexor should be connected to the dis- play, using the wsconscfg(8) command. It will then receive all key- strokes from all keyboards and, furthermore, keyboards can be dynamically attached and detached without further user interaction. Additionally, bell events generated for the display will be directed to all attached wsbell(4) devices. In a similar way, the window system will open the mouse multiplexor and receive all mouse events; mice can also be dynami- cally attached and detached. If a wskbd(4), wsbell(4), or wsmouse(4) device is opened despite having a mux it will be detached from the mux. It is also possible to inject events into a multiplexor from a user pro- gram.
FILES
For each mux device, /dev/wsmuxN there is a control device /dev/wsmuxctlN. The control device has a minor number 128 greater than the regular mux device. It can be used to control the mux even when it is open, e.g., by wsmuxctl(8). /dev/wsmouse a.k.a. /dev/wsmux0 /dev/wskbd a.k.a. /dev/wsmux1 /usr/include/dev/wscons/wsconsio.h

CAVEATS
If more than one type of keyboard is used, WSKBDIO_GTYPE will return the type of the first keyboard. NetBSD 9.0 August 13, 2019 NetBSD 9.0
