Starts a program, in the background, and returns three Go pipes of type (chan []byte), which are connected to the process's STDIN, STDOUT and STDERR. Bytes will be read from the wrapped program and written to the channels as quickly as possible, but there are no guarantees on speed or how many bytes are delivered per message in the channel. This routine does no buffering, however the wrapped process can use buffers, so you still might not get prompt delivery of your data. In general, most programs will use line buffering unless you can force them not to.

Channel length is the buffer length of the go pipes

This routine does no buffering, however the wrapped process can use buffers, so you still might not get prompt delivery of your data. In general, most programs will use line buffering unless you can force them not to.
