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.
