XkbFreeGeomOverlayKeys - Free keys in an overlay row
void XkbFreeGeomOverlayKeys (XkbRowPtr
row, int first, int
count, Bool free_all);
- - 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
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.
- Success
- The XkbFreeGeomOverlayKeys function returns Success if there are no
allocation or argument errors.
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
