Hi, I'm just trying to work out how to do it. Please find my latest attempt below. The docs aren't much help with this.

I'm playing around with uFFI and I'm having trouble figuring out how to provide a buffer to C. It looks like maybe ByteArray would be the type, but it's not working. Would some one be so kind as to show me an example with the C function gethostname? Thanks, Gerry
