.SH DESCRIPTION
|
|
.LP
|
|
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
|
|
.I sz_*
|
|
but never touch
|
|
.I num_*
|
|
(unless there is an allocation failure, in which case they reset both
|
|
.I sz_*
|
|
and
|
|
.I 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.
|
|
|
|
.I XkbAllocGeomKeys
|
|
allocates
|
|
.I num_needed
|
|
keys and adds them to the
|
|
.I row.
|
|
No initialization of the keys is done.
|
|
.SH DIAGNOSTICS
|
|
.TP 15
|
|
.B BadAlloc
|
|
Unable to allocate storage
|
|
.TP 15
|
|
.B BadValue
|
|
An argument is out of range
