XkbGetAutoResetControls(3) XKB FUNCTIONS XkbGetAutoResetControls(3)
XkbGetAutoResetControls - Gets the current values of the auto-reset controls
Bool XkbGetAutoResetControls ( dpy, auto_ctrls, auto_values )
Display * dpy ;
unsigned int * auto_ctrls ;
unsigned int * auto_values ;
connection to X server
specifies which bits in auto_values are relevant
1 bit => corresponding control has auto-reset on
You can configure the boolean controls to automatically be enabled or disabled when a pro-
gram 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 ter-
minated. 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.
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 suc-
cessfully backfill auto_ctrls and auto_values with the AutoReset control
attributes for this particular client.
