XkbAllocGeomOutlines - Allocate space for an arbitrary number of outlines to a shape

Status XkbAllocGeomOutlines (XkbShapePtr shape , int num_needed );

• - shape
      shape for which outlines should be allocated
• - num_needed
      number of new outlines 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. XkbAllocGeomOutlinesallocates space for num_neededoutlines in the specified shape.The outlines are not initialized. To free geometry outlines, use XkbFreeGeomOutlines.

BadAlloc
