XkbGetKeySyms(3) XKB FUNCTIONS XkbGetKeySyms(3)

XkbGetKeySyms - Obtain the symbols for a subset of the keys in a keyboard description

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

connection to X server
keycode of first key to get
number of keycodes for which syms desired
Xkb description to be updated

XkbGetKeySyms sends a request to the server to obtain the set of keysyms bound to num keys starting with the key whose keycode is first. It waits for a reply and returns the keysyms in the map.syms field of xkb. If successful, XkbGetKeySyms returns Success. The xkb parameter must be a pointer to a valid Xkb keyboard description.

If the client map in the xkb parameter has not been allocated, XkbGetKeySyms allocates and initializes it before obtaining the symbols.

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

The XkbGetKeySyms function returns Success if it gets a reply to a request to the server to obtain the set of keysyms bound to num keys starting with the key whose keycode is first.
