Subject: [Qemu-devel] [PATCH 6/8] linux-user: Check dump_write() return in elf_core_dump()
Date: Tue, 12 Jul 2016 13:02:17 +0100 [thread overview]
Message-ID: <1468324939-12221-7-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1468324939-12221-1-git-send-email-peter.maydell@linaro.org>
One of the calls to dump_write() in elf_core_dump() was missing
a check for failure (spotted by Coverity). Add the check to
bring it into line with the other calls from this function.
