       XkbGetKeyModifierMap  -  Update the modifier map for one or more of the keys in a keyboard


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


       - dpy  connection to X server

       - first
              keycode of first key to get

       - num  number of keys for which information is desired

       - xkb  keyboard description to update


       The  modmap  entry  of the client map is an array, indexed by keycode, specifying the real
       modifiers bound to a key. Each entry is a mask composed of a bitwise inclusive OR  of  the
       legal  real  modifiers:  ShiftMask,  LockMask,  ControlMask, Mod1Mask, Mod2Mask, Mod3Mask,
       Mod4Mask, and Mod5Mask. If a bit is set in a modmap entry, the corresponding key is  bound
       to that modifier.

       Pressing  or  releasing  the  key  bound  to a modifier changes the modifier set and unset
       state. The particular manner in  which  the  modifier  set  and  unset  state  changes  is
       determined by the behavior and actions assigned to the key.

       XkbGetKeyModifierMap  sends a request to the server for the modifier mappings for num keys
       starting with the key whose keycode is first.  It waits for a reply and places the results
       in the xkb->map->modmap array. If successful, XkbGetKeyModifier returns Success.

       If  the  map  component  of the xkb parameter has not been allocated, XkbGetKeyModifierMap
       allocates and initializes it.

       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 any allocation errors occur
       while obtaining the modifier map, XkbGetKeyModifierMap returns BadAlloc.


       BadAccess      The Xkb extension has not been properly initialized

       BadAlloc       Unable to allocate storage
