XkbGetAutoResetControls(3) XKB FUNCTIONS XkbGetAutoResetControls(3)
NAME
XkbGetAutoResetControls - Gets the current values of the auto-reset
controls
SYNOPSIS
Bool XkbGetAutoResetControls (Display *dpy, unsigned int *auto_ctrls,
unsigned int *auto_values);
ARGUMENTS
dpy connection to X server
auto_ctrls
specifies which bits in auto_values are relevant
auto_values
1 bit => corresponding control has auto-reset on
DESCRIPTION
You can configure the boolean controls to automatically be enabled or
disabled when a program exits. This capability is controlled via two
masks maintained in the X server on a per-client basis. There is no
client-side Xkb data structure corresponding to these masks. Whenever the
client exits for any reason, any boolean controls specified in the
auto-reset mask are set to the corresponding value from the auto-reset
values mask. This makes it possible for clients to "clean up after
themselves" automatically, even if abnormally terminated. The bits used
in the masks correspond to the EnabledControls control bits.
For example, a client that replaces the keyboard bell with some other
audible cue might want to turn off the AudibleBell control to prevent the
server from also generating a sound and avoid cacophony. If the client
were to exit without resetting the AudibleBell control, the user would be
left without any feedback at all. Setting AudibleBell in both the auto-
reset mask and auto-reset values guarantees that the audible bell will be
turned back on when the client exits.
XkbGetAutoResetControls backfills auto_ctrls and auto_values with the
AutoReset control attributes for this particular client. It returns True
if successful, and False otherwise.
RETURN VALUES
True The XkbGetAutoResetControls function returns True when it
successfully backfills auto_ctrls and auto_values with the
AutoReset control attributes for this particular client.
False The XkbGetAutoResetControls function returns False when it
does not successfully backfill auto_ctrls and auto_values
with the AutoReset control attributes for this particular
client.
