NAME
XkbFreeGeomOverlayKeys - Free keys in an overlay rowSYNOPSIS
-
void XkbFreeGeomOverlayKeys
(XkbRowPtr row,
int first,
int count,
Bool free_all);
ARGUMENTS
- - row
-
- row in which keys should be freed
- - first
- first key to be freed
- - count
- number of keys to be freed
- - free_all
- True => all keys are freed
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.
If
free_all
is True, all keys are freed regardless of the value of
first
and
count.
Otherwise, the number of keys specified by
count
are freed, beginning with the key specified by
first
in the specified row.
RETURN VALUES
- Success
- The XkbFreeGeomOverlayKeys function returns Success if there are no allocation or argument errors.
DIAGNOSTICS
- BadAlloc
- Unable to allocate storage
- BadValue
-
