NAME¶
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
