# HG changeset patch
# User Ian Campbell <ijc@xxxxxxxxxxxxxx>
# Date 1353432141 0
# Node ID e4525795eac22c7d199ceae8714e95ed660a00c4
# Parent bdd9c3e423d7f505f93edf413a92ad7b47ed9e39
libxl: ocaml: switch all functions over to take a context.
Since the context has a logger we can get rid of the logger built into these
bindings and use the xentoollog bindings instead.
The gc is of limited use when most things are freed with libxl_FOO_dispose,
so get rid of that too.
