From c2cdb4ad5c9398ef0d3310613107999f8d33c7ce Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Wed, 25 Feb 2009 17:43:07 +1100 Subject: [PATCH] Work around ndr_unpack failing on structures with relative pointers. This disgusting hack works around the fact that ndr_pull_struct_blob_all will always fail on structures with relative pointers. So, map ndr_unpack to ndr_pull_struct_blob_all only if we don't have any relative pointers in this structure.
