From: David Scott Date: Wed, 24 Apr 2013 10:39:04 +0000 (+0100) Subject: Add binding for virConnectSetKeepAlive X-Git-Tag: 0.6.1.3~4 X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=0ec198e7784de1a49672183c961a2498b6c85b90;p=ocaml-libvirt.git Add binding for virConnectSetKeepAlive This one is a 'one-off' but it ought to be possible to use the generator to create the function (it has signature 'conn, int, int : int') This function first appeared in libvirt version 0.9.8.
