From mboxrd@z Thu Jan 1 00:00:00 1970 From: Petr Vorel Date: Wed, 20 Mar 2019 22:57:07 +0100 Subject: [LTP] [PATCH 1/1] msgrcv/msgrcv08.c: Use struct msgbuf defined in Message-ID: <20190320215707.30268-1-petr.vorel@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it which requires to define _GNU_SOURCE. This fixes MUSL build. NOTE: char array from struct has usually length 1, the one from test had 16, but that's not a limitation. Fixes: eccd238da ("ipc/msgrcv: add new testcase msgrcv08") Reported-by: Dengke Du Signed-off-by: Petr Vorel --- Hi Li, what was the reason to use size 16? Kind regards, Petr PS: I found and fix this error independently while working on MUSL build fixes, but than found it was reported by Dengke Du in PR #177 [1].
