Subject: [PATCH] BaseTools/CommonLib: Fix unaligned API prototypes
Date: Sun, 8 Aug 2021 19:39:54 +0000 [thread overview]
Message-ID: <a533aec79f997e44595d5d863be29a63a1ac2199.1628449510.git.mhaeuser@posteo.de> (raw)
In-Reply-To: <b5220a578c737bcb167b93a7f9af55751770e540.1628449510.git.mhaeuser@posteo.de>
C prohibits not only dereferencing but also casting to unaligned
pointers. Thus, the current set of unaligned APIs cannot be called
safely. Update their prototypes to take VOID * pointers, which must
be able to represent any valid pointer.
