Guidance on how to write the chrome_native_messaging_host.exe would be very helpful.

[BenKey]

This is an excellent and well written document. It answers most of the questions about native messaging. Unfortunately, like so many other resources on this subject, it leaves the most important question unanswered. How do you actually write the chrome_native_messaging_host.exe application?

This document makes it clear that stdin and stdout are used to communicate with the host. However some vital information is left out.

• How is the information sent from the extension encoded? I have some information that suggests the first four bytes is a number that specifies packet length and the rest may be the packet data encoded as JSON but I am not certain of this.
• How to encode the information that is sent back to the extension?
• How does the chrome_native_messaging_host.exe application know when to exit?

A brief section on writing the chrome_native_messaging_host.exe application with a few code examples in different programming languages would be very useful.
