[libvirt] [PATCH] libvirt.c: fix virStateActive return value; document ...

The s/1/-1/ fix induces no semantic change, since the sole use of virStateActive tests solely for nonzero. From: Jim Meyering <meyering(a)redhat.com&gt; Date: Mon, 24 Nov 2008 15:52:55 +0100 Subject: [PATCH] libvirt.c: fix virStateActive return value; document some new functions * src/libvirt.c (virStateActive): Return -1 upon error, not 1, to be consistent with the other virState* functions.
