[SoX-users] how to specify null output file using libsox.lib?

[<xl...@so...>]

Hi,
 
I want to use effect stat and noiseprof in my application with libsox.lib. But I don't know how to specify the output file to 'null' just like using the command sox a.wav -n stat. In that command, the option '-n' specify a null output file, so, whant should I do with libsox.lib? Could anyone give me some advice?
 
Thank you.
