.TH XkbFreeControls 3 "libX11 1.7.0" "X Version 11" "XKB FUNCTIONS"
.SH NAME
XkbFreeControls \- Frees memory used by the ctrls member of an XkbDescRec structure
.SH SYNOPSIS
.HP
.B void XkbFreeControls
.BI "(\^XkbDescPtr " "xkb" "\^,"
.BI "unsigned int " "which" "\^,"
.BI "Bool " "free_all" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- xkb
Xkb description in which to free controls components
.TP
.I \- which
mask of components of ctrls to free
.TP
.I \- free_all
True => free everything + ctrls itself
.SH DESCRIPTION
.LP
.I XkbFreeControls 
frees the specified components of the 
.I ctrls 
field in the 
.I xkb 
keyboard description and sets the corresponding structure component values to NULL or zero. The 
.I which 
mask specifies the fields of 
.I 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 
.I free_all 
is True, 
.I XkbFreeControls 
frees every non-NULL structure component in the controls, frees the XkbControlsRec structure referenced by the 
.I ctrls 
member of 
.I xkb, 
and sets 
.I ctrls 
to NULL.
