XkbAllocControls(3) XKB FUNCTIONS XkbAllocControls(3) NAME XkbAllocControls - Allocates an XkbControlsRec structure in the XkbDe- scRec SYNOPSIS Status XkbAllocControls (XkbDescPtr xkb, unsigned int which); ARGUMENTS xkb Xkb description in which to allocate ctrls rec which mask of components of ctrls to allocate DESCRIPTION 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- trols. 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, Xk- bAllocControls 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. c s s s l l l l l l l l l l l l.
