XkbAllocGeomProps(3) XKB FUNCTIONS XkbAllocGeomProps(3)
NAME
XkbAllocGeomProps - Allocate geometry properties
SYNOPSIS
Status XkbAllocGeomProps (XkbGeometryPtr geom, int num_needed);
ARGUMENTS
geom geometry for which properties should be allocated
num_needed
number of new properties 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 para-
meter is not as expected.
XkbAllocGeomProps allocates space for num_needed properties and adds
them to the specified geometry geom. No initialization of the proper-
ties is done. A geometry property associates an arbitrary string with an
equally arbitrary name. Geometry properties can be used to provide hints
to programs that display images of keyboards, but they are not inter-
preted by Xkb. No other geometry structures refer to geometry proper-
ties.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
