From 9eb80eadd498fae2ad9eecbb89646b0cc4929cac Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 18 Oct 2012 16:49:29 +0200 Subject: [PATCH] qmp: add pull_event function 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.
