XkbResizeKeySyms(3)		  XKB FUNCTIONS 	     XkbResizeKeySyms(3)

NAME
     XkbResizeKeySyms - Change the number of symbols bound to a key

SYNOPSIS
     KeySym * XkbResizeKeySyms (XkbDescRec *xkb, int key, int needed);

ARGUMENTS
     xkb    keyboard description to be changed

     key    keycode for key to modify

     needed
	    new number of keysyms required for key

DESCRIPTION
     XkbResizeKeySyms reserves the space needed for needed keysyms and returns a
     pointer  to  the  beginning of the new array that holds the keysyms. It ad-
     justs the offset field of the key_sym_map entry for the  key  if  necessary
     and can also change the syms, num_syms, and size_syms fields of xkb->map if
     it  is  necessary	to reallocate the syms array.  XkbResizeKeySyms does not
     modify either the width or number of groups associated with the key.

     If needed is greater than the current number of keysyms for the key, XkbRe-
     sizeKeySyms initializes all new keysyms in the array to NoSymbol.

     Because the number of symbols needed by a key is normally computed as width
     * number of groups, and XkbResizeKeySyms does not modify either  the  width
     or  number of groups for the key, a discrepancy exists upon return from Xk-
     bResizeKeySyms between the space allocated for the keysyms and  the  number
     required.	The  unused  entries  in  the list of symbols returned by XkbRe-
     sizeKeySyms are not preserved across future calls to any of the map editing
     functions, so you must update the key symbol  mapping  (which  updates  the
     width  and  number  of groups for the key) before calling another allocator
     function. A call to XkbChangeTypesOfKey will update the mapping.

     If any allocation errors occur while resizing the number of  symbols  bound
     to the key, XkbResizeKeySyms returns NULL.

NOTES
     A change to the number of symbols bound to a key should be accompanied by a
     change  in  the  number of actions bound to a key. Refer to XkbResizeKeyAc-
     tions for more information on changing the number of  actions  bound  to  a
     key.
