Lines of code - yes, not counting lines of comments at the beginning.
Typedef - I don't recollect typedef.
You commented on my code pointing out that an absence of va_end at the
end is non-portable. Also you were not happy with my choice of signed
type for bufsz argument.
Your other suggestion was to provide va_list variant of the function in
addition to vararg (i.e. ...) variant.
