ShowInitIcon is a tiny piece of code that lets you easily display INIT icons. It should work with most C or Pascal compilers, and has been tested with CodeWarrior, MPW and Symantec. This is version 1.0.1.
This code is free for use in any project.
Bruce Partridge offers an enhanced version of this code, which is able to use Navigation Services and the new 32 bit icns. I haven't personally tested it.
