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.
