XkbResizeKeyActions(3)						   XKB FUNCTIONS					    XkbResizeKeyActions(3)

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.
