       XkbGetControls - Finds the current state of Xkb server controls


       Status   XkbGetControls   (Display   *display,   unsigned  long  which,
              XkbDescPtr xkb);


       - display
              connection to X server

       - which
              mask of controls requested

       - xkb  keyboard description for controls information


       XkbGetControls  queries  the   server   for   the   requested   control
       information, waits for a reply, and then copies the server's values for
       the requested information into the ctrls structure of the xkb argument.
       Only  those  components  specified  by  the which parameter are copied.
       Valid values for which are any combination of the masks listed in Table
       1 that have "ok" in the which column.

       Table  1  shows  the actual values for the individual mask bits used to
       select controls for modification and to enable and disable the control.
       Note that the same mask bit is used to specify general modifications to
       the parameters used to configure the control (which), and to enable and
       disable  the control (enabled_ctrls). The anomalies in Table 1 (no "ok"
       in column) are for controls that have no configurable  attributes;  and
       for  controls  that  are  not  boolean controls and therefore cannot be
       enabled or disabled.

       If xkb->ctrls is NULL,  XkbGetControls  allocates  and  initializes  it
       before  obtaining  the values specified by which.  If xkb->ctrls is not
       NULL,  XkbGetControls  modifies  only  those  portions  of   xkb->ctrls
       corresponding to the values specified by which.

       XkbGetControls  returns  Success  if  successful; otherwise, it returns
       BadAlloc if it cannot obtain sufficient storage,  BadMatch  if  xkb  is
       NULL or which is empty, or BadImplementation.

       The num_groups field in the ctrls structure  is  always  filled  in  by
       XkbGetControls, regardless of which bits are selected by which.

       BadMatch       A compatible version of Xkb was  not  available  in  the
                      server or an argument has correct type and range, but is
                      otherwise invalid
