[GRASS5] grass .. how does write on display

[Somesh Agarwal]

hi people
I am new to grass and while looking at grass code I found this find io.c
in which
to write a text to display (from paint dir) we write the whole of
$GISBASE/font/fontname  file contents to the display socket ,
I did not understand what is happening exactly , can someone throw
more light into the issue ,
my basic purpose is to create some new font support for grass ..
thanks a lot
somesh
