XkbFreeControls(3)				    XKB FUNCTIONS				   XkbFreeControls(3)

XkbFreeControls - Frees memory used by the ctrls member of an XkbDescRec structure
void XkbFreeControls ( xkb, which, free_all ) XkbDescPtr xkb; unsigned int which; Bool free_all;
- xkb Xkb description in which to free controls components - which mask of components of ctrls to free - free_all True => free everything + ctrls itself
XkbFreeControls frees the specified components of the ctrls field in the xkb keyboard description and sets the corresponding structure component values to NULL or zero. The which mask specifies the fields of ctrls to be freed and can contain any of the controls components specified in Table 1. 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 con- trols that are not boolean controls and therefore cannot be enabled or disabled. Table 1 Controls Mask Bits --------------------------------------------------------------------------- Mask Bit which or enabled Value changed_ctrls _ctrls --------------------------------------------------------------------------- XkbRepeatKeysMask ok ok (1L<<0) XkbSlowKeysMask ok ok (1L<<1) XkbBounceKeysMask ok ok (1L<<2) XkbStickyKeysMask ok ok (1L<<3) XkbMouseKeysMask ok ok (1L<<4) XkbMouseKeysAccelMask ok ok (1L<<5) XkbAccessXKeysMask ok ok (1L<<6) XkbAccessXTimeoutMask ok ok (1L<<7) XkbAccessXFeedbackMask ok ok (1L<<8) XkbAudibleBellMask ok (1L<<9) XkbOverlay1Mask ok (1L<<10) XkbOverlay2Mask ok (1L<<11) XkbIgnoreGroupLockMask ok (1L<<12) XkbGroupsWrapMask ok (1L<<27) XkbInternalModsMask ok (1L<<28) XkbIgnoreLockModsMask ok (1L<<29) XkbPerKeyRepeatMask ok (1L<<30) XkbControlsEnabledMask ok (1L<<31) XkbAccessXOptionsMask ok ok (XkbStickyKeysMask | XkbAccessXFeedbackMask) XkbAllBooleanCtrlsMask ok (0x00001FFF) XkbAllControlsMask ok (0xF8001FFF) If free_all is True, XkbFreeControls frees every non-NULL structure component in the controls, frees the Xkb- ControlsRec structure referenced by the ctrls member of xkb, and sets ctrls to NULL.
