From 1d795fa57b9f0b9c23cecfe0329a5e551ea903ee Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Wed, 12 Jan 2005 07:03:29 +0000 Subject: r4700: first attempt at a composite async function, smb_composite_loadfile(), which combineds ntcreatex, readx and close into a single call that behaves just like a normal libcli async call.
