XkbAllocGeomOverlayKeys(3) XKB FUNCTIONS XkbAllocGeomOverlayKeys(3)
NAME
XkbAllocGeomOverlayKeys - Allocate keys in an overlay row
SYNOPSIS
Status XkbAllocGeomOverlayKeys (XkbOverlayRowPtr row, int num_needed);
ARGUMENTS
row section for which rows should be allocated
num_needed
number of new rows 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.
XkbAllocGeomOverlayKeys allocates num_needed keys and adds them to the
row. No initialization of the keys is done.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
