void XkbFreeGeomPoints (XkbOutlinePtr outline, int first, int count, Bool free_all);
outline in which points should be freed
first point to be freed
number of points to be freed
True => all points 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 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.
The XkbFreeGeomPoints function returns Success when there are no allocation or argument errors.
