geometry to be updated
.TP
.I \- name
name of the new section
.TP
.I \- sz_rows

.TP
.I \- sz_doodads
number of doodads to reserve in the section
.TP
.I \- sz_overlays
number of overlays to reserve in the section
.SH DESCRIPTION
.LP
Xkb provides functions to add a single new element to the top-level keyboard
geometry. In each case the
.I num_ *
fields of the corresponding structure is incremented by 1. These functions do
not change
.I sz_*
unless there is no more room in the array. Some of these functions fill in the
values of the element's structure from the arguments. For other functions, you
must explicitly write code to fill the structure's elements.
The top-level geometry description includes a list of
.I geometry properties.
A geometry property associates an arbitrary string with an equally arbitrary
name. Programs that display images of keyboards can use geometry properties as
hints, but they are not interpreted by Xkb. No other geometry structures refer
to geometry properties.
A keyboard geometry contains an arbitrary number of sections.
.I XkbAddGeomSection
adds one section to an existing keyboard geometry
.I geom.
The new section contains space for the number of rows, doodads, and overlays
specified by
.I sz_rows, sz_doodads,
and
.I sz_overlays.
The new section is allocated and zeroed and given the name specified by
.I name.
If a section with name
.I name
already exists in the geometry, a pointer to the existing section is returned.
.I XkbAddGeomSection
returns NULL if any of the parameters is empty or if it was not able to allocate
space for the section. To allocate space for an arbitrary number of sections to
a geometry, use
.I XkbAllocGeomSections.
