How to retrieve a proto file "option" from within a c++ program?

[Bruce Buffam]

I have a sequence of the following expressions in my proto file as follows:

...

extend google.protobuf.FileOptions {

     // The foo service semantic version

     string foo_service = 1001;

}

option (foo_service) = "1.1.0";

...

Is there a c++ code snippet somewhere that shows how to retrieve the value of foo_service?

Rgds,

Bruce

I've got this for a field option, file should be fairly similar  (using Message::descriptor()->file())

if (field->options().HasExtension(the_option)) {

    return field->options().GetExtension(the_option);

  }
