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.
