Subject: [PATCH 05/15] Add SYSV message queue test
Date: Tue, 01 Nov 2016 14:25:00 -0000 [thread overview]
Message-ID: <1478010323-13076-6-git-send-email-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <1478010323-13076-1-git-send-email-adhemerval.zanella@linaro.org>
This patch adds a simple SYSV message queue test to check for correct
argument passing on kernel. The idea is neither to be an extensive
testing nor to check for any specific Linux test.
* sysvipc/Makefile (tests): Add test-sysvmsg.
* sysvipc/test-sysvmsg.c: New file.
* test-skeleton.c (FAIL_UNSUPPORTED): New define.
