XkbGetKeyModifierMap(3)


NAME

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

SYNOPSIS

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

ARGUMENTS

   - 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

DESCRIPTION

   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.

DIAGNOSTICS

   BadAccess      The Xkb extension has not been properly initialized

   BadAlloc       Unable to allocate storage
