XkbFreeControls(3)
NAME
XkbFreeControls - Frees memory used by the ctrls member of an XkbDescRec structure
SYNOPSIS
void XkbFreeControls (XkbDescPtr xkb, unsigned int which, Bool
free_all);
ARGUMENTS
- xkb Xkb description in which to free controls components
- which
mask of components of ctrls to free
- free_all
True => free everything + ctrls itself
DESCRIPTION
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.
