[En-Nut-Discussion] Reading from file

[Ernst Stippl]

Hi Maciek!

        FILE *stronka = NULL;
...
                                fprintf_P(stdout, PSTR("%s"), data);
//                                fwrite(data, 1, n, stronka);

I guess the 12 chars are printed by the fprintf_P and then the fwrite to
"stronka" - which is "NULL" - does no good .....

Regards
ernst

Thx for help! It really works! But there is another problem...
If you take a look at my first post about reading from file, then you can 
see, that I commented one line - it is that one with fwrite function. So... 
if I uncomment that line then 12 first characters are displayed (including 
"\n" and "\r") and after that my whole device restarts. I really don't know 
why.

Any ideas?

Thx!

Maciek

Oops, I forgot

n = _read(fd, data, size - 1);
