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.
