(Fwd) Re: DOSFS bug fixes, IDE drivers and sample released

[Angelo Fraietta]

I have implemented this into my app, hwoever, when I try to examine the 
file, I get zero bytes.
I did the following

    fd = open(nvram_file,O_WRONLY | O_CREAT | O_TRUNC,S_IREAD|S_IWRITE);
    if (fd <0)
        {
            printf ("Unable to open %s\r\n", nvram_file);
        }
    else
        {
            unsigned i;
            for (i = 0; i < 255; i++)
                {
                    char c = (char) i;
                    int bytes = write(fd, &c, 1);
                    printf ("Wrote %u bytes \r\n", bytes);
                }
            close(fd);
            printf ("Close file\r\n");
            fileio_part_table_initialize ();           
        }

I got the correct output to my display, however, the file written is 
zero bytes. Any idea as to what I am doing wrong?
