I don't think there's any real convention in the CRuby codebase.

Keep in mind strncpy has its own flaws - if the source string is exactly =
the length of the destination buffer, it won't null terminate. =20

Personally I've never really been a fan of strncpy. strcpy is perfectly s=
afe if you know what you're doing. If you don't, you'll probably run into=
 problems with strncpy too.
