Documentation for libraries still mentions @ccallable

[s-broda]

The docs for libraries still mentions @ccallable: "The library is expected to provide C-callable functions for the functionality it is providing, defined using the Base.@ccallable macro". From the upgrade instructions, this seems to no longer be true? Also, the code following the sentence doesn't use @ccallable.

I could make a PR, but I'm not sure how this behaviour changed: "All C-callable functions will be exported and made available to programs that link to the library."

It's only for the main entry point in apps that you should not use @ccallable. For libraries, it should be used.

Ah, I see, thanks. However, the code snippet in that paragraph,

function increment(count::Cint)::Cint
    count += 1
    println("Incremented count: $count")
    return count
end

doesn't use @ccallable, which could be a bit confusing.

Yes, that should indeed have it! I added it back in 6a3bdcc

Great, thanks! I'll close this.
