From 9a95fe49c848d2711dcdcf4c407e626e41e4657f Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 13 Aug 2009 02:14:19 +0200 Subject: core: add assert macros for verifying calling context This adds pa_assert_io_context() and pa_assert_ctl_context() in addition to a few related macros. When called they will fail when the current execution context is not IO resp. not control context.
