XkbFreeControls - Frees memory used by the ctrls member of an XkbDescRec
structure
void XkbFreeControls (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
controls that are not boolean controls and therefore cannot be enabled or
disabled.

If free_all is True, XkbFreeControls frees every
non-NULL structure component in the controls, frees the XkbControlsRec
structure referenced by the ctrls member of xkb, and sets
ctrls to NULL.
