NAME
       XkbKeyNumSyms - Returns the total number of keysyms for the key corresponding to keycode

SYNOPSIS
       int XkbKeyNumSyms 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.

       XkbKeyNumSyms returns the total number of keysyms for the key corresponding to keycode.
