All samples come from the commit 340fd9528cc3b26d22fe30ee1628c8c3f2b8c53b
of [wasm-c-api][https://github.com/WebAssembly/wasm-c-api].

Every user should be familiar with *APIs* listed in
[wasm.h][https://github.com/WebAssembly/wasm-c-api/blob/master/include/wasm.h].

all [examples][https://github.com/WebAssembly/wasm-c-api/tree/master/example] are
very helpful for learning.

Currently, we support partial of *APIs* and are going to support the rest of
them in next releases.

Supported APIs:
