Subject: [PATCH 0/3] Add offsetofp() and offsetofendp() for pointer arithmetic
Date: Thu, 05 Nov 2026 18:16:15 +0100 [thread overview]
Message-ID: <20261105-offsetof-v1-0-4153f5c10edc@arm.com> (raw)
A common usage pattern for offsetof() is the following:
offsetof(typeof(*ptr), member)
Condense this operation to one macro for a more maintainable code base.
