6 XkbAllocControls - Allocates an XkbControlsRec structure in the XkbDe‐
7 scRec

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

13 - xkb Xkb description in which to allocate ctrls rec
14 - which
16 mask of components of ctrls to allocate
17
19 The need to allocate an XkbControlsRec structure seldom arises; Xkb
20 creates one when an application calls XkbGetControls or a related func‐
21 tion. For those situations where there is not an XkbControlsRec struc‐
22 ture allocated in the XkbDescRec, allocate one by calling XkbAllocCon‐
23 trols.
24 XkbAllocControls allocates the ctrls field of the xkb parameter, ini‐
26 tializes all fields to zero, and returns Success. If the ctrls field is
27 not NULL, XkbAllocControls simply returns Success. If xkb is NULL,
28 XkbAllocControls reports a BadMatch error. If the ctrls field could not
29 be allocated, it reports a BadAlloc error.
30 The which mask specifies the individual fields of the ctrls structure
32 to be allocated and can contain any of the valid masks defined in Table
33 1. (SHOULD THIS COMMENT BE LEFT IN????) Because none of the currently
34 existing controls have any structures associated with them, which is
35 currently of little practical value in this call.
36 Table 1 shows the actual values for the individual mask bits used to
38 select controls for modification and to enable and disable the control.
39 Note that the same mask bit is used to specify general modifications to
40 the parameters used to configure the control (which), and to enable and
41 disable the control (enabled_ctrls). The anomalies in the table (no
42 "ok" in column) are for controls that have no configurable attributes;
43 and for controls that are not boolean controls and therefore cannot be
44 enabled or disabled.
