NAME
XkbAllocGeomSections - Allocate geometry sectionsSYNOPSIS
-
Status XkbAllocGeomSections
(XkbGeometryPtr geom,
int num_needed);
ARGUMENTS
- - geom
-
- geometry for which sections should be allocated
- - num_needed
- number of new sections 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.
XkbAllocGeomSections
allocates
num_needed
sections and adds them to the geometry
geom.
No initialization of the sections is done.
To free geometry sections, use
XkbFreeGeomSections.
DIAGNOSTICS
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
