Too many things for a glance. It requires a perusal.
#include <stdio.h>
#include <stdlib.h>

fprintf(stderr, "usage error\n");
return EXIT_FAILURE;
}

if (option == 'b') {
imode = "rb";
omode = "wb";
}
if (option == 't') {
/* This may or may not do something useful on your system */

/* popular extension for text mode. */
imode = "rt";
omode = "wt";

I will definately save this code and study it. I really do no use do
so
maybe this will open my eyes to it some.
