Detailed Description

template<typename Stream>
class asio::buffered_write_stream< Stream >

Adds buffering to the write-related operations of a stream.

The buffered_write_stream class template can be used to add buffering to the synchronous and asynchronous write operations of a stream.

Thread Safety
Distinct objects: Safe.
Shared objects: Unsafe.
Concepts:
AsyncReadStream, AsyncWriteStream, Stream, SyncReadStream, SyncWriteStream.
