NAME¶
XkbFreeGeomPoints - Free points in a outline
SYNOPSIS¶
void XkbFreeGeomPoints (XkbOutlinePtr
outline, int first, int
count, Bool free_all);
ARGUMENTS¶
- - outline
- outline in which points should be freed
- - first
- first point to be freed
- - count
- number of points to be freed
- - free_all
- True => all points 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 points are freed regardless of the value of
>i first and
count. Otherwise, the number of points specified by
count are freed, beginning with the point specified by
first in
the specified outline.
RETURN VALUES¶
- Success
- The XkbFreeGeomPoints function returns Success when there are no
allocation or argument errors.
DIAGNOSTICS¶
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
