NAME

6       XkbGetControls - Finds the current state of Xkb server controls
7

SYNOPSIS

9       Status  XkbGetControls  (Display  *display, unsigned long which, XkbDe‐
10              scPtr xkb);
11

ARGUMENTS

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

DESCRIPTION

22       XkbGetControls queries the server for the  requested  control  informa‐
23       tion,  waits  for  a reply, and then copies the server's values for the
24       requested information into the ctrls structure  of  the  xkb  argument.
25       Only  those  components  specified  by  the which parameter are copied.
26       Valid values for which are any combination of the masks listed in Table
27       1 that have "ok" in the which column.
28
29       Table  1  shows  the actual values for the individual mask bits used to
30       select controls for modification and to enable and disable the control.
31       Note that the same mask bit is used to specify general modifications to
32       the parameters used to configure the control (which), and to enable and
33       disable  the control (enabled_ctrls). The anomalies in Table 1 (no "ok"
34       in column) are for controls that have no configurable  attributes;  and
35       for  controls  that  are  not  boolean controls and therefore cannot be
36       enabled or disabled.

67
68       If xkb->ctrls is NULL,  XkbGetControls  allocates  and  initializes  it
69       before  obtaining  the values specified by which.  If xkb->ctrls is not
70       NULL, XkbGetControls modifies only those portions of xkb->ctrls  corre‐
71       sponding to the values specified by which.
72
73       XkbGetControls  returns  Success  if  successful; otherwise, it returns
74       BadAlloc if it cannot obtain sufficient storage,  BadMatch  if  xkb  is
75       NULL or which is empty, or BadImplementation.
76
77       To  free  the  ctrls  member of a keyboard description, use XkbFreeCon‐
78       trols.
79
80       The num_groups field in the ctrls structure  is  always  filled  in  by
81       XkbGetControls, regardless of which bits are selected by which.
82

RETURN VALUES

84       Success        The  XkbGetControls function returns Success if success‐
85                      ful.
