.SH NAME
XkbAllocGeomSections \- Allocate geometry sections
.SH SYNOPSIS
.B Status XkbAllocGeomSections
(
.I geom,
.I num_needed
)
.br
      XkbGeometryPtr \fIgeom\fP\^;
.br
      int \fInum_needed\fP\^;
.if n .ti +5n

.SH ARGUMENTS
.TP
.I \- geom
geometry for which sections should be allocated
.TP
.I \- num_needed
number of new sections 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 XkbAllocGeomSections 
allocates 
.I num_needed 
sections and adds them to the geometry 
.I geom. 
No initialization of the sections is done.

To free geometry sections, use 
.I XkbFreeGeomSections.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
