Like the man said `there are no semantics defined'.

Successfully writing `n' objects of zero size?  Just where will it all end?

I can see it now, `Programming in C+++':

    fp = fopen("/dev/null", "r+");
    p = malloc(0);
    fread(p, 0, 42, fp);
    p += 0;
    fwrite(p, 0, 42, fp);

Choose a better _algorithm_ and leave library routine breaking to the experts.
