XkbFreeControls(3) XKB FUNCTIONS 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 Ta-
ble 1.
Table 1 shows the actual values for the individual mask bits used to se-
lect 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 en-
abled or disabled.

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