Re: [boost] Iostreams 'drain' algorithm proposal

Hello list.

New here, but a Boost user so thought it was time I started lurking with a view to contributing.

When using boost::iostreams, I find I frequently need/implement a 'drain' algorithm. This is identical to boost::iostreams::copy, except that it doesn't close the Sink. This allows mutiple sources to be 'drained' into a single sink.

Unless there is a generic algorithm for doing this that I have missed, I'd like to propose the addition of the 'drain' algorithm to boost::iostreams.

I have a patch, should there be any interest.

I like this idea. I think a good way to implement it might be to use Boost.Parameters, like so: copy(src, sink, close_sink=false) -- Jonathan Turkanis www.kangaroologic.com
