Subject: Re: [edk2-devel] [PATCH v2 1/1] MdePkg: Add STATIC_ASSERT macro
Date: Wed, 14 Aug 2019 13:50:27 +0000 [thread overview]
Message-ID: <4A89E2EF3DFEDB4C8BFDE51014F606A14E4D0EC7@SHSMSX104.ccr.corp.intel.com> (raw)
In-Reply-To: <20190813081644.53963-2-vit9696@protonmail.com>
Can you add the sample usage of new macro STATIC_ASSERT?
Or, give the link of static_assert or _Static_assert.
If so, the developer knows how to use them in source code.
Thanks
Liming
