XkbFreeGeomPoints - Free points in a outline

void XkbFreeGeomPoints (XkbOutlinePtr outline , int first , int count , Bool free_all );

• - 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

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_allis True, all points are freed regardless of the value of >i first and count.Otherwise, the number of points specified by countare freed, beginning with the point specified by firstin the specified outline.

• Success
                 The XkbFreeGeomPoints function returns Success when there are no allocation or argument errors.

BadAlloc

               Unable to allocate storage

BadValue

               An argument is out of range
