XkbAllocControls(3)              XKB FUNCTIONS             XkbAllocControls(3)

       XkbAllocControls  - Allocates an XkbControlsRec structure in the XkbDe-

       Status XkbAllocControls ( xkb, which )
             XkbDescPtr xkb;
             unsigned int which;

       - xkb  Xkb description in which to allocate ctrls rec

       - which
              mask of components of ctrls to allocate

       The need to allocate an XkbControlsRec  structure  seldom  arises;  Xkb
       creates one when an application calls XkbGetControls or a related func-
       tion. For those situations where there is not an XkbControlsRec  struc-
       ture  allocated in the XkbDescRec, allocate one by calling XkbAllocCon-

       XkbAllocControls allocates the ctrls field of the xkb  parameter,  ini-
       tializes all fields to zero, and returns Success. If the ctrls field is
       not NULL, XkbAllocControls simply returns  Success.  If  xkb  is  NULL,
       XkbAllocControls reports a BadMatch error. If the ctrls field could not
       be allocated, it reports a BadAlloc error.

       The which mask specifies the individual fields of the  ctrls  structure
       to be allocated and can contain any of the valid masks defined in Table
       1.  (SHOULD THIS COMMENT BE LEFT IN????)  Because none of the currently
       existing  controls  have  any structures associated with them, which is
       currently of little practical value in this call.

       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  the  table  (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.
