passing strings to Go

[Michael Krisher]

I've tried a few different ways now and assume I may be missing something obvious.

All I want to do is pass a Ruby string to Go:

// Go function

func receive(s string) string {

  fmt.Println("Go String:", s)

  return s

}

# ruby code

module PassStringToGo

  extend FFI::Library

  ffi_lib File.expand_path("./receive_string.so", File.dirname(__FILE__))

  attach_function :receive, [:string], :string

end

str = "Ruby String"

PassStringToGo.receive(str)

The output in the Go function is blank.

Do I have to use a pointer?

Thanks,
