NAME
       XkbResizeKeyActions - Change the number of actions bound to a key

SYNOPSIS
       XkbAction * XkbResizeKeyActions (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 key-
       code  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 XkbChangeType-
       sOfKey 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.
