Subject: [PATCH 5/5] stddef.h: Remove sizeof_field macro
Date: Tue, 24 Sep 2019 16:21:14 +0530	[thread overview]
Message-ID: <20190924105114.110535-6-pankaj.laxminarayan.bharadiya@intel.com> (raw)
In-Reply-To: <20190924105114.110535-1-pankaj.laxminarayan.bharadiya@intel.com>

Now we have sizeof_member macro to find the size of a member of a
struct.

sizeof_field  macro is not getting used any more hence remove it.
Also modify the offsetofend macro to get rid of it.
