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.
If
free_all
is True, all shapes in the geometry are freed regardless of the values of
first
and
count.
Otherwise,
count
shapes are freed, beginning with the shape specified by
first.
RETURN VALUES
Success
The XkbFreeGeomShapes function returns Success when there are no allocation
or argument errors.
