I just searched my emails for the old threads that added these converters: strcmp : https://www.mail-archive.com/[email protected]/msg29799.html secure_memcmp: https://www.mail-archive.com/[email protected]/msg37552.html The secure_memcmp discussion is particularly interesting here, because Willy and me shortly discussed memcmp as well.
