Hi!

Here's a patch set for documenting mem*(3) and strn*(3) functions as
provided in <memory.h>.  This should put a stop to the misunderstanding
and misuse of these functions as handling strings; they handle bytes and
nonstrings (and in some cases, strings can be used as nonstrings or as
byte arrays, but very carefully).

This header is quite portable: {Free,Net,Open}BSD, glibc, and musl, at
least and since forever.

The C Committee is discussing standardization of <memory.h>, so let's
give it a bump.


Have a lovely night!
Alex
