XkbResizeKeySyms(3)						   XKB FUNCTIONS					       XkbResizeKeySyms(3)

NAME

       XkbResizeKeySyms - Change the number of symbols bound to a key

SYNOPSIS

       KeySym * XkbResizeKeySyms ( xkb, key, needed )
	     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.

NAME

       XkbResizeKeyActions - Change the number of actions bound to a key

SYNOPSIS

       XkbAction * XkbResizeKeyActions ( xkb, key, needed )
	     XkbDescRec * xkb;
	     int key;
	     int needed;

ARGUMENTS

       - xkb  keyboard description to change

       - key  keycode of key to change

       - needed
	      new number of actions required

DESCRIPTION

       The  xkb parameter points to the keyboard description containing the key whose number of actions is to be changed. The key parameter is the
       keycode of the key to change, and needed specifies the new number of actions required for the key.

       XkbResizeKeyActions reserves the space needed for the actions and returns a pointer to the beginning  of  the  new  array  that	holds  the
       actions. It can change the acts, num_acts, and size_acts fields of xkb->server if it is necessary to reallocate the acts array.

       If  needed is greater than the current number of keysyms for the key, XkbResizeKeyActions initializes all new actions in the array to NoAc-
       tion.

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

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

NOTES

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