NAME

6       XkbSetControls  -  Copies  changes  to the X server based on a modified
7       ctrls structure in a local copy of the keyboard description
8

SYNOPSIS

10       Bool XkbSetControls (Display *display, unsigned long which,  XkbDescPtr
11              xkb);
12

ARGUMENTS

14       - display
15              connection to X server
16
17       - which
18              mask of controls requested
19
20       - xkb  keyboard description for controls information
21

DESCRIPTION

23       For  each  bit that is set in the which parameter, XkbSetControls sends
24       the corresponding values from the xkb->ctrls field to the server. Valid
25       values  for  which  are  any combination of the masks listed in Table 1
26       that have "ok" in the which column.
27
28       Table 1 shows the actual values for the individual mask  bits  used  to
29       select controls for modification and to enable and disable the control.
30       Note that the same mask bit is used to specify general modifications to
31       the parameters used to configure the control (which), and to enable and
32       disable the control (enabled_ctrls). The anomalies  in  the  table  (no
33       "ok"  in column) are for controls that have no configurable attributes;
34       and for controls that are not boolean controls and therefore cannot  be
35       enabled or disabled.

65
66       If xkb->ctrls is NULL, the server does not support a compatible version
67       of Xkb, or the Xkb extension has not been properly initialized, XkbSet‐
68       Controls returns False. Otherwise, it sends the request to the X server
69       and returns True.
70
71       Note that changes to  attributes  of  controls  in  the  XkbControlsRec
72       structure are apparent only when the associated control is enabled, al‐
73       though the corresponding values are still updated in the X server.  For
74       example, the repeat_delay and repeat_interval fields are ignored unless
75       the RepeatKeys control is enabled (that is, the X  server's  equivalent
76       of  xkb->ctrls  has XkbRepeatKeyMask set in enabled_ctrls).  It is per‐
77       missible to modify the attributes of a control in one call  to  XkbSet‐
78       Controls  and enable the control in a subsequent call. See XkbChangeEn‐
79       abledControls for more information on enabling and disabling controls.
80
81       Note that the enabled_ctrls field is itself a control - the EnabledCon‐
82       trols  control. As such, to set a specific configuration of enabled and
83       disabled boolean controls, you must set enabled_ctrls to the  appropri‐
84       ate  bits  to enable only the controls you want and disable all others,
85       then specify the XkbControlsEnabledMask in a call to XkbSetControls.
86
87       Because this is somewhat awkward if all you want to do  is  enable  and
88       disable controls, and not modify any of their attributes, a convenience
89       function is also provided for this purpose, XkbChangeEnabledControls.

RETURN VALUES

92       True           The XkbSetControls function returns True when  it  sends
93                      the request to the X server.
94
95       False          The   XkbSetControls   function   returns   False   when
96                      xkb->ctrls is NULL, the server does not support  a  com‐
97                      patible  version  of  Xkb,  or the Xkb extension has not
98                      been properly initialized.

DIAGNOSTICS

101       BadAlloc       Unable to allocate storage
102
103       BadMatch       A compatible version of Xkb was  not  available  in  the
104                      server or an argument has correct type and range, but is
