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 ac- tions required for the key. XkbResizeKeyActions reserves the space needed for the actions and re- turns a pointer to the beginning of the new array that holds the ac- tions. 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 ei- ther the width or number of groups for the key, a discrepancy exists on return from XkbResizeKeyActions between the space allocated for the ac- tions and the number required. The unused entries in the list of ac- tions 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) be- fore 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. SEE ALSO XkbChangeTypesOfKey(3), XkbResizeKeySyms(3) 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. X Version 11 libX11 1.6.12 XkbResizeKeyActions(3)
