CDataStream operator+ (const CDataStream &a, const CDataStream &b)
 

Detailed Description

Double ended buffer combining vector and stream-like interfaces.

and << read and write unformatted data using the above serialization templates.

Fills with data in linear time; some stringstream implementations take N^2 time.
