- geometry for which shapes should be allocated
- - num_needed
- number of new shapes required
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.
XkbAllocGeomShapes allocates space for num_needed shapes in the specified geometry geom. The shapes are not initialized.
To free geometry shapes, use XkbFreeGeomShapes.
