XkbFreeGeomColors - Free geometry colors

void XkbFreeGeomColors (XkbGeometryPtr geom , int first , int count , Bool free_all );

• - geom
      geometry in which colors should be freed
• - first
      first color to be freed
• - count
      number of colors to be freed
• - free_all
      True => all colors 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 colors are freed regardless of the value of firstor count.Otherwise, countcolors are freed beginning with the one specified by first.

BadAlloc

               Unable to allocate storage

BadValue

               An argument is out of range
