XkbAllocGeomOverlayRows

NAME
XkbAllocGeomOverlayRows - Allocate rows in a overlay
SYNOPSIS
-
Status XkbAllocGeomOverlayRows
(XkbOverlayPtr overlay,
int num_needed);
ARGUMENTS
- - overlay
-
- section for which rows should be allocated
- - num_needed

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.
XkbAllocGeomOverlayRows
allocates
num_needed
rows and adds them to the
overlay.
No initialization of the rows is done.
To free rows in an overlay, use
XkbFreeGeomOverlayRows.
DIAGNOSTICS
- BadAlloc
-
Unable to allocate storage
- BadValue
-
An argument is out of range
