[Boost-users] array sink of unknown size

Hello,

I need a filtering_ostream that efficiently yields a char* and it's size 
(i.e., it allocates the memory it needs). I have no way of knowing
or predicting the number of chars resulting from uncompressing the input 
(?). For efficiency it would be nice to specify an estimate
and a "chunking" size, but the filtering_ostream would actually allocate 
all that is needed.

I looked at this:
    boost::iostreams::stream< boost::iostreams::array_sink >

but it seems to need a terminating char* or a size in its ctor.

What is recommended?

Thanks!
