XkbGetAutoResetControls - Man Page

Bool XkbGetAutoResetControls (Display *dpy, unsigned int  *auto_ctrls, unsigned int  *auto_values);

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

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.

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.
