XkbAllocGeomSections - Allocate geometry sections

Status XkbAllocGeomSections (XkbGeometryPtr geom , int num_needed );

• - geom
      geometry for which sections should be allocated
• - num_needed
      number of new sections 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. XkbAllocGeomSectionsallocates num_neededsections and adds them to the geometry geom.No initialization of the sections is done. To free geometry sections, use XkbFreeGeomSections.

BadAlloc
