XkbAllocGeomColors — Allocate geometry colors

Synopsis

Status XkbAllocGeomColors (XkbGeometryPtr geom, int num_needed);

Arguments

- geom

geometry for which colors should be allocated

- num_needed

number of new colors required

Description

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.

XkbAllocGeomColors allocates space for num_needed colors and adds them to the specified geometry geom. A color name is a string whose interpretation is not specified by Xkb. All other  geometry data structures refer to colors using their indices in this global list  or pointers to colors in this list.

Diagnostics

BadAlloc

Unable to allocate storage

BadValue

An argument is out of range
