FireWyrmNativeMessageHost quits unexpectedly

[LIANG ZHOU]

Hello,

  I'm using the latest version of Firebreath 2.0. I found that when I use printf("") funciton in my plugin code, like in get_version(), the host process will quit unexpectedly, with the error message "An Unexpected Error has ocurred:  Host disconnected" displayed in web browser console.

std::string KIYPluginAPI::get_version()

{

    printf("get_version");

    

    return FBSTRING_PLUGIN_VERSION;

}

 

While debugging, there is no exception thrown by host process.

Any help is appreciated, thanks!

Yep, that's absolutely going to happen; the reason is that it uses STDOUT to communicate with the browser.

I recommend you use logging instead.

Thinking about it a bit more, you might be able to use STDERR instead and have it pass through to the output from the browser; I still recommend logging, though.
