Subject: [dpdk-dev] [PATCH v4 03/10] lib: use C99 syntax for zero-size arrays
Date: Wed, 13 Jul 2016 15:02:40 +0200 [thread overview]
Message-ID: <ee00454352cddb078e5f685e9aa843bef7914457.1468413397.git.adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <cover.1468413396.git.adrien.mazarguil@6wind.com>
Exported header files used by applications should allow the strictest
compiler flags. Language extensions used in many places must be explicitly
marked or removed to avoid warnings and compilation failures.
The extension keyword is used whenever the C99 syntax cannot do it.
This commit prevents the following errors:
error: ISO C forbids zero-size array `[...]'
