WSMOUSE(4) Device Drivers Manual WSMOUSE(4)
NAME
wsmouse - generic mouse support in wscons
SYNOPSIS
wsmouse* at pms? mux 0 (PS/2 mouse, including
``IntelliMouse''-compatible wheel mice)
wsmouse* at ums? mux 0 (USB mouse)
wsmouse* at uts? mux 0 (USB touchscreen)
wsmouse* at lms? mux 0 (Logitech bus mouse, i386 only)
wsmouse* at mms? mux 0 (Microsoft InPort mouse, i386 only)
wsmouse0 at ams? mux 0 (Apple ADB mouse)
wsmouse* at btms? mux 0 (Bluetooth mouse)
wsmouse* at lkms? mux 0 (DEC VSXXX serial mice)
DESCRIPTION
The wsmouse driver is an abstraction layer for mice within the wscons(4)
framework. It is attached to the hardware specific mouse drivers and
provides a character device interface which returns struct wscons_event
via read(2). For use with X servers, "mouse events" can be generated.
The wsconsctl(8) utility gives access to several configurable details
that affect this driver.
Ioctls
The following ioctl(2) calls are provided by the wsmouse driver or by
devices which use it. Their definitions are found in
dev/wscons/wsconsio.h.
WSMOUSEIO_GETPARAMS (struct wsmouse_parameters)
WSMOUSEIO_SETPARAMS (struct wsmouse_parameters)
Obtain and set various mouse parameters as a key/value set.
Currently these primarily relate to touchpads. The
structure struct wsmouse_parameters is defined as follows:
struct wsmouse_param {
enum wsmousecfg key;
int value;
};
struct wsmouse_parameters {
struct wsmouse_param *params;
unsigned int nparams;
};
The number of parameters to read or write must be specified
in nparams. For each parameter, when WSMOUSEIO_GETPARAMS
is used, a key must be specified. When WSMOUSEIO_SETPARAMS
is used, a key and a value must be specified. A single
ioctl may retrieve up to WSMOUSECFG_MAX nparams.
WSMOUSEIO_GETREPEAT (struct wsmouse_repeat)
Retrieve the current automatic button repeating
configuration. The structure returned is as follows:
struct wsmouse_repeat {
unsigned long wr_buttons;
unsigned int wr_delay_first;
unsigned int wr_delay_decrement;
unsigned int wr_delay_minimum;
};
The wr_buttons field is a bit mask that specifies which
buttons send press and release events periodically while
they are physically held down. The least significant bit
corresponds to button 0.
The other three fields describe the frequency upon which
these automatic events are sent. wr_delay_first specifies
the milliseconds before the first repeated event is sent.
wr_delay_decrement is used to calculate the delay between
the most recently generated event and the forthcoming one:
the previous delay is taken and it is decreased by the
value given in this variable. wr_delay_minimum specifies
the minimum delay, in milliseconds, between two consecutive
events.
WSMOUSEIO_SETREPEAT (struct wsmouse_repeat)
Set the automatic button repeating configuration. See
WSMOUSEIO_GETREPEAT above for more details.
WSMOUSEIO_SETVERSION (int)
Set the wscons_event protocol version. The default is 0
for binary compatibility. The latest version is always
available as WSMOUSE_EVENT_VERSION, and is currently 1.
All new code should use a call similar to the below to
ensure the correct version is returned.
int ver = WSMOUSE_EVENT_VERSION;
if (ioctl(fd, WSMOUSEIO_SETVERSION, &ver) == -1)
err(EXIT_FAILURE, "cannot set version");
