void XkbFreeGeomRows (XkbSectionPtr section , int first , int count , Bool free_all );

• - section
      section in which rows should be freed
• - first
      first row to be freed
• - count
      number of rows to be 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 rows are freed regardless of the value of firstand count.Otherwise, the number of rows specified by countare freed, beginning with the row specified by firstin the specified section.

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

BadAlloc

               Unable to allocate storage

BadValue

               An argument is out of range
