/* ** (c) COPYRIGHT MIT 1995. ** Please first read the full copyright statement in the file COPYRIGH. */This module contains the routines for handling the set of active sockets currently in use by the multithreaded clients. It is an internal module to the Library, the application interface is implemented in the Event Module. Look for more information in the Multithread Specifications.
This module is implemented by HTNet.c, and it is a part of the W3C Reference Library.

HTNet
object is the core of the request queue
management. This object contains information about the socket
descriptor, the input read buffer etc. required to identify and
service a request.
