Hello there

This code comes from my operating system project, written in Crystal. The target platform was AMD64, so that's why it uses 64-Bit integers all over the place. The whole thing isn't open (yet?), but I stopped working on it so..

Take what you want from it, however a short source description, e.g. using a in-source comment, to this gist or to me would be really neat :)

Writing a dynamic library in Crystal, and calling it from C

• Download all files.
• Build the Crystal part:

crystal build --release --cross-compile --prelude ./no_main library.cr
              ^ You can leave this out
                        ^ We want to link ourselves!
 ^ Use our custom prelude!

print_message_function = -> (message : Void*) do

  return Pointer(Void).null

thread1 = uninitialized LibC::PthreadT
thread2 = uninitialized LibC::PthreadT
message1 = "Thread 1"

What's this PR do?

Where should the reviewer start?

How should this be manually tested?

Any background context you want to provide?

What are the relevant tickets?

Screenshots (if appropriate)

Questions:

• Is there a blog post?
• Does the knowledge base need an update?
• Does this add new (Python) dependencies which need to be added to chef?
