NAME

6       XkbResizeKeyActions - Change the number of actions bound to a key
7

SYNOPSIS

9       XkbAction * XkbResizeKeyActions (XkbDescRec *xkb, int key, int needed);
10

ARGUMENTS

12       - xkb  keyboard description to change
13
14       - key  keycode of key to change
15
16       - needed
17              new number of actions required
18

DESCRIPTION

20       The xkb parameter points to the keyboard description containing the key
21       whose number of actions is to be changed. The key parameter is the key‐
22       code  of  the key to change, and needed specifies the new number of ac‐
23       tions required for the key.
24
25       XkbResizeKeyActions reserves the space needed for the actions  and  re‐
26       turns  a  pointer  to the beginning of the new array that holds the ac‐
27       tions. It can change  the  acts,  num_acts,  and  size_acts  fields  of
28       xkb->server if it is necessary to reallocate the acts array.
29
30       If  needed  is  greater than the current number of keysyms for the key,
31       XkbResizeKeyActions initializes all new actions in the array  to  NoAc‐
32       tion.
33
34       Because  the  number of actions needed by a key is normally computed as
35       width * number of groups, and XkbResizeKeyActions does not  modify  ei‐
36       ther the width or number of groups for the key, a discrepancy exists on
37       return from XkbResizeKeyActions between the space allocated for the ac‐
38       tions  and  the  number required. The unused entries in the list of ac‐
39       tions returned by XkbResizeKeyActions are not preserved  across  future
40       calls  to  any of the map editing functions, so you must update the key
41       actions (which updates the width and number of groups for the key)  be‐
42       fore  calling another allocator function. A call to XkbChangeTypesOfKey
43       updates these.
44
45       If any allocation errors occur while resizing  the  number  of  actions
46       bound to the key, XkbResizeKeyActions returns NULL.

NOTES

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