.SH NAME
XkbAllocGeomOverlays \- Allocate overlays in a section
.SH SYNOPSIS
.B Status XkbAllocGeomOverlays
(
.I section,
.I num_needed
)
.br
XkbSectionPtr \fIsection\fP\^;
.br
int \fInum_needed\fP\^;
.if n .ti +5n

.SH ARGUMENTS
.TP
.I \- section
section for which overlays should be allocated
.TP
.I \- num_needed
number of new overlays required
.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.
.I XkbAllocGeomOverlays
allocates
.I num_needed
overlays and adds them to the
.I section.
No initialization of the overlays is done.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadValue
An argument is out of range
