[Qemu-devel] [PATCH v2 32/45] qmp: add pull_event function


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH v2 32/45] qmp: add pull_event function
Date: Wed, 26 Sep 2012 17:56:38 +0200

This function is unlike get_events in that it makes it easy to process
one event at a time.  This is useful in the mirroring test cases, where
we want to process just one event (BLOCK_JOB_ERROR) and leave the others
to a helper function.
