XkbGetAccessXTimeout(3) XKB FUNCTIONS XkbGetAccessXTimeout(3)
NAME
XkbGetAccessXTimeout - Queries the current AccessXTimeout options for a keyboard device
SYNOPSIS
Bool XkbGetAccessXTimeout (Display *display, unsigned int device_spec, unsigned short
*timeout_rtrn, unsigned int *ctrls_mask_rtrn, unsigned int *ctrls_values_rtrn,
unsigned short *options_mask_rtrn, unsigned short *options_values_rtrn);
ARGUMENTS
- display
unsigned short
- device_spec
device to query, or XkbUseCoreKbd
- timeout_rtrn
delay until AccessXTimeout, seconds
- ctrls_mask_rtrn
backfilled with controls to modify
- ctrls_values_rtrn
backfilled with on/off status for controls
- options_mask_rtrn
backfilled with ax_options to modify
- options_values_rtrn
backfilled with values for ax_options
DESCRIPTION
In environments where computers are shared, features such as SlowKeys present a problem:
if SlowKeys is on, the keyboard can appear to be unresponsive because keys are not
accepted until they are held for a certain period of time. To help solve this problem, Xkb
provides an AccessXTimeout control to automatically change the enabled/disabled state of
any boolean controls and to change the value of the AccessXKeys and AccessXFeedback con-
trol attributes if the keyboard is idle for a specified period of time.
When a timeout as specified by AccessXTimeout occurs and a control is consequently modi-
fied, Xkb generates an XkbControlsNotify event.
XkbGetAccessXTimeout sends a request to the X server to obtain the current values for the
AccessXTimeout attributes, waits for a reply, and backfills the values into the appropri-
ate arguments. The parameters options_mask_rtrn and options_values_rtrn are backfilled
with the options to modify and the values for ax_options, which is a field in the XkbCon-
trolsRec structure. XkbGetAccessXTimeout returns True if successful; if a compatible ver-
sion of the Xkb extension is not available in the server, XkbGetAccessXTimeout returns
False.
RETURN VALUES
True The XkbGetAccessXTimeout returns True when it successfully sends a request
to the X server to obtain the current values for the AccessXTimeout
attributes, waits for a reply, and backfills the values into the appropri-
ate arguments.
False The XkbGetAccessXTimeout funtion returns False if a compatible version of
the Xkb extension is not available in the server.
