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 sz_* but never touch num_*
(unless there is an allocation failure, in which case they reset both
sz_* and 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.
XkbAllocGeomProps allocates space for num_needed
properties and adds them to the specified geometry geom. No
initialization of the properties is done. A geometry property associates an
arbitrary string with an equally arbitrary name. Geometry properties can be
used to provide hints to programs that display images of keyboards, but they
are not interpreted by Xkb. No other geometry structures refer to geometry
properties.
