|
|
.SH DESCRIPTION
|
|
.LP
|
|
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
|
|
.I auto-reset mask
|
|
are set to the corresponding value from the
|
|
.I 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.
|
|
|
|
.I XkbGetAutoResetControls
|
|
backfills
|
|
.I auto_ctrls
|
|
and
|
|
.I auto_values
|
|
with the AutoReset control attributes for this particular client. It returns
|
|
True if successful, and False otherwise.
|
|
.SH "RETURN VALUES"
|
|
.TP 15
|
|
True
|
|
The
|
|
.I XkbGetAutoResetControls
|
|
function returns True when it successfully backfills
|
|
.I auto_ctrls
|
|
and
|
|
.I auto_values
|
|
with the AutoReset control attributes for this particular client.
|
|
.TP 15
|
|
False
|
|
The
|
|
.I XkbGetAutoResetControls
|
|
function returns False when it does not successfully backfill
|
|
.I auto_ctrls
|
|
and
|
|
.I auto_values
|
|
with the AutoReset control attributes for this particular client.
