DESCRIPTION

38       In  environments  where computers are shared, features such as SlowKeys
39       present a problem: if SlowKeys is on, the keyboard can appear to be un‐
40       responsive because keys are not accepted until they are held for a cer‐
41       tain period of time. To help solve this problem, Xkb  provides  an  Ac‐
42       cessXTimeout control to automatically change the enabled/disabled state
43       of any boolean controls and to change the value of the AccessXKeys  and
44       AccessXFeedback control attributes if the keyboard is idle for a speci‐
45       fied period of time.
46
47       When a timeout as specified by AccessXTimeout occurs and a  control  is
48       consequently modified, Xkb generates an XkbControlsNotify event.
49
50       XkbGetAccessXTimeout sends a request to the X server to obtain the cur‐
51       rent values for the AccessXTimeout attributes, waits for a  reply,  and
52       backfills the values into the appropriate arguments. The parameters op‐
53       tions_mask_rtrn and options_values_rtrn are backfilled with the options
54       to  modify  and the values for ax_options, which is a field in the Xkb‐
55       ControlsRec structure.  XkbGetAccessXTimeout returns True  if  success‐
56       ful;  if  a compatible version of the Xkb extension is not available in
57       the server, XkbGetAccessXTimeout returns False.

RETURN VALUES

60       True           The XkbGetAccessXTimeout returns True when  it  success‐
61                      fully sends a request to the X server to obtain the cur‐
62                      rent values for the AccessXTimeout attributes, waits for
63                      a  reply,  and backfills the values into the appropriate
64                      arguments.
65
66       False          The XkbGetAccessXTimeout function  returns  False  if  a
67                      compatible version of the Xkb extension is not available
68                      in the server.
