Take a look at cursesterm.c in the curses_terminal_update() function 
around line 682.  You'll see two for loops that looks like this:

   for (y = 0; y < tn5250_display_height(display); y++) {
...
      for (x = 0; x < tn5250_display_width(display); x++) {

These loop through all the positions on the screen and find out what is in 
each position with this line:

         c = tn5250_display_char_at(display, y, x);

The if statement immediately following that is what checks to see if c is 
an attribute or a normal character.
