Well, I'm so proud of my baby. It's still in testing. If you see any bugs let me know. It's a simple encryption program for Windows. I had dome some work with .so in Linux, so I figured I'd give .dll files a shot. Here is all the code, ans a Makefile. I compliled it with MinGW (a GCC port for WIndows) with no warnings other than about a def file.

int choice = -9;
choice = menu();
switch (choice)

fprintf(stderr, "This line should never be seen! Quitting\n");
exit(EXIT_FAILURE);
