[Qemu-devel] [RFC][PATCH 06/12] coroutine: Add qemu_coroutine_self()


From: Stefan Hajnoczi
Subject: [Qemu-devel] [RFC][PATCH 06/12] coroutine: Add qemu_coroutine_self()
Date: Sat, 22 Jan 2011 09:29:21 +0000

Add a function to get the current coroutine.  There is always a current
coroutine, either the "leader" (default main coroutine) or a specific
coroutine created with qemu_coroutine_create().
