Option 1: This patch (all callers have to worry about NULL buffers, but checking for output is a simple pointer check).
Option 2: Guarantee that outbuf/errbuf are allocated, even if to the empty string. Caller always has to free the result, and empty output check requires checking if *outbuf=='\0'.
Personally, I prefer option 2. Thoughts?
2 seems safer.
I vote for the second version too. Matthias
