28 // Description: Defines a template derived from std::basic_streambuf which uses
29 //      a chain to perform i/o. The template has the following parameters:
30 //      Ch - The character type.
31 //      Tr - The character traits type.
32 //      Alloc - The allocator type.
33 //      Access - Indicates accessibility of the chain interface; must be either
34 //          public_ or protected_; defaults to public_.
