Subject: [PATCH v4 09/19] libcflat: add abort() and assert()
Date: Thu, 10 Apr 2014 18:56:50 +0200	[thread overview]
Message-ID: <1397149020-3501-10-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1397149020-3501-1-git-send-email-drjones@redhat.com>

The test framework may have external dependencies. assert() provides
the ability to abort when those dependencies aren't met. However,
assert() should only be used for unlikely conditions. We can provide
more informative messages with printf() for the more likely problems.
