XkbKeySymsOffset(3)			  XKB FUNCTIONS 		      XkbKeySymsOffset(3)

NAME
       XkbKeySymsOffset  - Returns the offset of the two-dimensional array of keysyms for the key
       corresponding to keycode

SYNOPSIS
       int XkbKeySymsOffset macro ( xkb, keycode )
	     XkbDescPtr xkb;
	     KeyCode keycode;

ARGUMENTS
       - xkb  Xkb description of interest

       - keycode
	      keycode of interest

DESCRIPTION
       The key width and number of groups associated with a key are used to  form  a  small  two-
       dimensional  array  of  KeySyms for a key. This array may be different sizes for different
       keys. The array for a single key is stored as a	linear	list,  in  row-major  order.  The
       arrays  for  all  of the keys are stored in the syms field of the client map. There is one
       row for each group associated with a key and one column for each level. The  index  corre-
       sponding to a given group and shift level is computed as:

	    idx = group_index * key_width + shift_level

       The offset field of the key_sym_map entry for a key is used to access the beginning of the
       array.

       XkbKeySymsOffset returns the offset of the two-dimensional array of keysyms  for  the  key
       corresponding to keycode.
