18 Xkb provides functions to add a single new element to the top-level
19 keyboard geometry. In each case the num_ * fields of the corresponding
20 structure is incremented by 1. These functions do not change sz_* un‐
21 less there is no more room in the array. Some of these functions fill
22 in the values of the element's structure from the arguments. For other
23 functions, you must explicitly write code to fill the structure's ele‐
24 ments.
25 The top-level geometry description includes a list of geometry proper‐
27 ties. A geometry property associates an arbitrary string with an
28 equally arbitrary name. Programs that display images of keyboards can
29 use geometry properties as hints, but they are not interpreted by Xkb.
30 No other geometry structures refer to geometry properties.
31 An outline consists of an arbitrary number of points. XkbAddGeomOut‐
33 line adds an outline to the specified shape by reserving sz_points
34 points for it. The new outline is allocated and zeroed. XkbAddGeomOut‐
35 line returns NULL if any of the parameters is empty or if it was not
36 able to allocate space. To allocate space for an arbitrary number of
37 outlines to a shape, use XkbAllocGeomOutlines.
