XkbAllocGeomSectionDoodads — Allocate doodads that are specific to a section
Status XkbAllocGeomSectionDoodads (XkbSectionPtr section, int num_needed);
- - section
section for which doodads should be allocated
- - num_needed
number of new doodads 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.
XkbAllocGeomSectionDoodads allocates num_needed doodads and adds them to the specified section. No initialization of the doodads is done.
To free geometry doodads, use XkbFreeGeomDoodads.
