XkbAllocGeomOutlines(3) XKB FUNCTIONS XkbAllocGeomOutlines(3)
NAME
XkbAllocGeomOutlines - Allocate space for an arbitrary number of outlines
to a shape
SYNOPSIS
Status XkbAllocGeomOutlines (XkbShapePtr shape, int num_needed);
ARGUMENTS
shape shape for which outlines should be allocated
num_needed
number of new outlines 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.
XkbAllocGeomOutlines allocates space for num_needed outlines in the
specified shape. The outlines are not initialized.
To free geometry outlines, use XkbFreeGeomOutlines.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
