Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

While I realize that this is a rhetorical question, I will repeat my standard claim that every str* function should be deprecated.
Except strlen, though I guess you can replace with memchr in C11.
Ok, fine, you can have `str[n]len`. But that's it.
strstr, strchr, ... - basically all the ones only taking const char * are fine.
No. str[n]len for conversion from legacy NUL-terminated strings, and then everything is explicit-length beyond that boundary.
Going to disagree on null-termination being legacy. In many places it's safer, & of course simpler. And its a public contract outside C (pathnames etc.).
I don’t think that it’s actually safer, and I know that it’s always less efficient.
Base,len pair is more versatile/powerful (use substr in-place) & may be more efficient, but also subject to error using wrong len.
Most users should be using an abstraction built over (base,len) that does bookkeeping for them, anyway.
Only if your code is really heavy on string ops. Otherwise it's just an extra layer of complexity. Many uses of strings get by fine with just treating them as immutable inputs, possibly with a few snprintfs internally.
