Log Message:
vis(3): Make maxolen unsigned size_t, not ssize_t.
It is initialized once either to *dlen, which is unsigned size_t, or
to wcslen(start) * MB_MAX_LEN + 1, and wcslen returns unsigned size_t
too. So there appears to have never been any reason for this to be
signed.

A non-terminated char array is not a C-string. The term C-string is not ambiguous. This is something that, amazingly, even Internet trolls appear to agree on. However, they do disagree as to the spelling of the terminating character's name, which is why I think it's best to elide it altogether. -- thorpej

Ah, but you're giving up the opportunity to use indirection to solve the problem. By calling it a "C-string", then those who care what the standard calls the terminating character can go look it up! :-) -- thorpej

I couldn't find the definition for null-terminated though. This is different than the NULL #define Not to be confused with the all zeros ASCII charater, whose mnemonic is NUL, which is where some pressure to use NUL terminated comes from. I agree that it's usage is narrower and really only relevant for certain ASCII and ASCII-derived character sets, which is why the standard chose the spelling it did. Since all the 'C' standards[*] use "null-terminated" and "null character", it's likely best to use that terminology because there is a source of truth for its definition in case of ambiguity or doubt. Warner [*] I've not gone the extra mile and checked to see if K used this phrase, to be honest.

I feel like I've usually seen it as NUL-terminated. I thought it was in /usr/share/misc/style but I must have been thinking of a different style guide. `NUL' is better than `null' or `NULL' here because it's not a null pointer, unlike, e.g., the execve argv terminator. Even if the string isn't US-ASCII, what character encoding calls a nonzero byte `NUL'? `NUL' is better than `zero' or `0' here because it's unambiguously the all-bits-zero byte, not the US-ASCII encoding of `0' (i.e., decimal 48 or 0x30). `C string' is ambiguous because there are also char arrays that function as strings but which are not guaranteed to be NUL-terminated, as strncpy is intended for.
