21 Xkb provides functions to add a single new element to the top-level
22 keyboard geometry. In each case the num_ * fields of the corresponding
23 structure is incremented by 1. These functions do not change sz_*
24 unless there is no more room in the array. Some of these functions fill
25 in the values of the element's structure from the arguments. For other
26 functions, you must explicitly write code to fill the structure's ele‐
27 ments.

29 The top-level geometry description includes a list of geometry proper‐
30 ties. A geometry property associates an arbitrary string with an
31 equally arbitrary name. Programs that display images of keyboards can
32 use geometry properties as hints, but they are not interpreted by Xkb.
33 No other geometry structures refer to geometry properties.
34
35 A geometry contains an arbitrary number of shapes, each of which is
36 made up of an arbitrary number of outlines. XkbAddGeomShape adds a
37 shape to a geometry geom by allocating space for sz_outlines outlines
38 for it and giving it the name specified by name. If a shape with name
39 name already exists in the geometry, a pointer to the existing shape is
40 returned. XkbAddGeomShape returns NULL if any of the parameters is
41 empty or if it was not able to allocate space. To allocate space for an
42 arbitrary number of geometry shapes, use XkbAllocGeomShapes.
