XkbGetKeyActions(3) XKB FUNCTIONS XkbGetKeyActions(3)

XkbGetKeyActions - Update the actions (the key_acts array) for a subset of the keys in a keyboard description

Status XkbGetKeyActions (Display *dpy, unsigned int first, unsigned int num, XkbDescPtr xkb);

connection to X server
keycode of first key of interest
number of keys desired
pointer to keyboard description where result is stored

XkbGetKeyActions sends a request to the server to obtain the actions for num keys on the keyboard starting with key first. It waits for a reply and returns the actions in the server->key_acts field of xkb. If successful, XkbGetKeyActions returns Success. The xkb parameter must be a pointer to a valid Xkb keyboard description.

If the server map, in the xkb parameter, has not been allocated, XkbGetKeyActions allocates and initializes it before obtaining the actions.

If the server does not have a compatible version of Xkb, or the Xkb extension has not been properly initialized, XkbGetKeyActions returns BadAccess. If num is less than 1 or greater than XkbMaxKeyCount, XkbGetKeyActions returns BadValue. If any allocation errors occur, XkbGetKeyActions returns BadAlloc.

The Xkb extension has not been properly initialized
