XkbFreeGeomOverlayRows - Free rows in an overlay
void XkbFreeGeomOverlayRows (XkbSectionPtr
overlay, int first, int
count, Bool free_all);
- - overlay
- section in which rows should be freed
- - first
- first row to be freed
- - count
- number of rows to be freed
- - free_all
- True => all rows are freed
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 rows are freed regardless of the
value of first and count. Otherwise, the number of rows
specified by count are freed, beginning with the row specified by
first in the specified overlay.
- Success
- The XkbFreeGeomOverlayRows function returns Success if there are no
allocation or argument errors.
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
