help About fifo and thread

hi, my problem is

i have 10 thread for produces double two dimensional array these will produces 2d array 400 times ,then i have a thread to takes a two dimensional array then it inverse , and most 10 array can be in the fifo , and threads given takes one by one, now my problem is , i cant send 2d array to fifo, then i cant read array with fifo , i just send(write) char* to fifo then i read char

, how can i send double dimensional array to fifo or another alternative.. thanks

XkbKeySymEntry(3)						   XKB FUNCTIONS						 XkbKeySymEntry(3)

NAME

       XkbKeySymEntry -  Returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
       corresponding to keycode

SYNOPSIS

       KeySym XkbKeySymEntry macro ( xkb, keycode, shift, grp )
	     XkbDescPtr xkb;
	     KeyCode keycode;
	     int shift;
	     int grp;

ARGUMENTS

       - xkb  Xkb description of interest

       - keycode
	      keycode of interest

       - shift
	      shift level of interest

       - grp  group 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 corresponding 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.

       XkbKeySymEntry  returns	the  keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
       corresponding to keycode.
