.TP
.I \- device_spec
device to query, or XkbUseCoreKbd
.TP
.I \- timeout_rtrn
delay until AccessXTimeout, seconds

.SH DESCRIPTION
.LP
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 control
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 modified,
Xkb generates an XkbControlsNotify event.
.I 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
appropriate arguments. The parameters
.I options_mask_rtrn
and
.I options_values_rtrn
are backfilled with the options to modify and the values for
.I ax_options,
which is a field in the XkbControlsRec structure.
.I XkbGetAccessXTimeout
returns True if successful; if a compatible version of the Xkb extension is not
available in the server,
.I XkbGetAccessXTimeout
returns False.
.SH "RETURN VALUES"
.TP 15
True
The
.I 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 appropriate arguments.
.TP 15
False
The
.I XkbGetAccessXTimeout
funtion returns False if a compatible version of the Xkb extension is not
available in the
server.
