NAME¶
XkbFreeGeomOverlayKeys - Free keys in an overlay row
SYNOPSIS¶
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
- An argument is out of range
