Add buffer stream interface #504

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
This needs to be done inside the library, rather than be left up to the user, 
for performance reasons:

File based stream interface keeps a small buffer that it copies bytes into/ 
writes bytes out of. If we are streaming from a buffer, then there is no need 
for this small buffer - we can use the input buffer itself
for this, and save a memcpy.

This should reduce some of the memory traffic.

HI Aaron, 

If I'm not mistaken, you've got an implementation in one of your GitHub branch ?
So do I but only for input stream at the moment.

I'm waiting for a full transition to GitHub to do more on this.

Yes, I have an implementation. Let's discuss further when Github transition is 
complete.
