Return Values

Remarks
This function will post a message on a bus which will call registered functions. This part will be delayed and is not synchronous with the WASM module. This is why you cannot have a return value to know if a message has been delivered to someone, only a return to know if there has been some internal error (eg: buf = nullptr and size != 0 for instance).
