Subject: [PATCH v5 08/10] seccomp: Enhance test_harness with an assert step mechanism
Date: Wed, 22 Feb 2017 02:26:30 +0100
Message-ID: <20170222012632.4196-9-mic@digikod.net> (raw)
In-Reply-To: <20170222012632.4196-1-mic@digikod.net>

This is useful to return an information about the error without being
able to write to TH_LOG_STREAM.

Helpers from test_harness.h may be useful outside of the seccomp
directory.
