XkbResizeKeyActions(3) XKB FUNCTIONS XkbResizeKeyActions(3)
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.
