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 adjusts 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, XkbResizeKeySyms 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 XkbResizeKeySyms between the space allocated for the
       keysyms and the number required. The unused entries in the list of symbols returned by XkbResizeKeySyms 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 XkbRe-
       sizeKeyActions for more information on changing the number of actions bound to a key.
