Hi,
yes, error(0,...) is a bit like warn(), it returns to the programm.

That supports what my man page says:

" If  status has a nonzero value, then error() calls exit(3) to terminate
       the program using the given value as the exit status."

may be you want an add on like:

"Otherwise error() returns."

Betreff: error.3: What happens if status = 0

Hi Michael,

I think it's not quite clear what happens when status = 0; for
error[_at_line](3) from the text of the manual page.  From the glibc
documentation[1], it seems that error(0, ...) is similar to warn(...),
isn't it?

Thanks,

Alex
