You could call it either. My problems are
1) that given a format string I don't know in advance how much work space is
needed so cannot accurately malloc, for sure, enough space
2) since this can be called in an error handler I really don't want it calling
malloc().
Hence it lives in this limbo. I don't even know a way to add a good error
checking that detects if the buffer is long enough. All in all it is bad ugly
code, any suggestions on improvements would be appreciated.
