Use a startup hook if you want code run every time Factor starts up. Probably necessary for most init calls.
Top level code like your example would only run the first time the vocabulary is USE'd. You could also have every word call something like a `maybe-init` before doing what they would do with the library. > On Mar 1, 2017, at 9:13 AM, Alexander Ilin <ajs...@yandex.ru> wrote: > > Hello! > > What's the proper way of making sure an external library is initialized? > > I'm making bindings for libsodium, and it wants `int sodium_init()` to be > called before any other functions are used. > > I'm thinking about simply adding the following code at the end of my FFI > vocab: > > ``` > ERROR: sodium-init-fail ; > > !
