func StdCopy

func StdCopy(dstout, dsterr io.Writer, src io.Reader) (written int64, err error)

StdCopy is a modified version of io.Copy.

StdCopy will demultiplex `src`, assuming that it contains two streams, previously multiplexed together using a StdWriter instance. As it reads from `src`, StdCopy will write to `dstout` and `dsterr`.

StdCopy will read until it hits EOF on `src`. It will then return a nil error. In other words: if `err` is non nil, it indicates a real underlying error.

`written` will hold the total number of bytes written to `dstout` and `dsterr`.
