Detailed Description

Implementation of a dynamic extensible buffer.

This file defines the base_pipe and pipe classes that implement an extensible buffer capable of storing data efficiently with automatic capacity management. These classes are widely used in the asynchronous I/O system for managing input and output data.

stream & operator<<	(	stream &	os,
		qb::allocator::pipe< char > const &	p )

Stream operator to display the content of a pipe<char>

Template Parameters

stream

Type of output stream

Parameters

os	Output stream
p	Pipe to display

Returns

Reference to the output stream
