NAME¶
XkbAllocGeomPoints - Allocate points in an outline
SYNOPSIS¶
Status
XkbAllocGeomPoints (XkbOutlinePtr outline, int
num_needed);
ARGUMENTS¶
- - outline
- outline for which points should be allocated
- - num_needed
- number of new points 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.
XkbAllocGeomPoints allocates space for
num_needed points in the
specified
outline. The points are not initialized.
DIAGNOSTICS¶
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
