About

I decided to learn WASI, but I faced the fact that for WebAssembly Text (WAT) there is no description of the functions that WASI provides.

(I found nothing for NodeJS runtime)

I got all the functions names, but the interfaces are not described, as well as what it does.

Therefore, I began to collect knowledge, mainly from the C resources of the NodeJS, the meaning of functions from the docks of Wasmtime runtime (it differs from the NodeJS's API for WASI).

I write down knowledge in the form of primitive work with functions in this repo.
