Subject: [LTP] [PATCH] msgrcv02: Add negative msgtyp tests
Date: Tue, 12 Oct 2021 10:28:58 +0100 [thread overview]
Message-ID: <20211012092858.29992-1-rpalethorpe@suse.com> (raw)
Test that we do not get higher message types. Also that -1 msgtyp is not
misinterpreted as INT_MAX by using MSG_EXCEPT.
Signed-off-by: Richard Palethorpe <rpalethorpe@suse.com>
Suggested-by: Cyril Hrubis <chrubis@suse.cz>
