Thanks, I'll check this tomorrow at work.
I was also thinking about:
http://forge.scilab.org/index.php/p/csv-readwrite/
as its purpose is close to the one of my C routine (read 16 bit tiff file).
I can't browse the sources now, so I don't know whether the comments are 
adapted to my level (newbeeee) in this field...
