.TH XkbFreeGeomOverlayKeys __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbFreeGeomOverlayKeys \- Free keys in an overlay row
.SH SYNOPSIS
.HP
.B void XkbFreeGeomOverlayKeys
.BI "(\^XkbRowPtr " "row" "\^,"
.BI "int " "first" "\^,"
.BI "int " "count" "\^,"
.BI "Bool " "free_all" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- row
row in which keys should be freed
.TP
.I \- first
first key to be freed
.TP
.I \- count
number of keys to be freed
.TP
.I \- free_all
True => all keys are freed
.SH DESCRIPTION
.LP
Xkb provides a number of functions to allocate and free subcomponents of a
keyboard geometry. Use these functions to create or modify keyboard geometries.
Note that these functions merely allocate space for the new element(s), and it
is up to you to fill in the values explicitly in your code. These allocation
functions increase
.I sz_*
but never touch
.I num_*
(unless there is an allocation failure, in which case they reset both
.I sz_*
and
.I num_*
to zero). These functions return Success if they succeed, BadAlloc if they are
not able to allocate space, or BadValue if a parameter is not as expected.
If
.I free_all
is True, all keys are freed regardless of the value of
.I first
and
.I count.
Otherwise, the number of keys specified by
.I count
are freed, beginning with the key specified by
.I first
in the specified row.
.SH "RETURN VALUES"
.TP 15
Success
The XkbFreeGeomOverlayKeys function returns Success if there are no allocation
or argument errors.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadValue
An argument is out of range
