/*****
 ***** Module Info
 *****/

/*! \file isc/socket.h
 * \brief Provides TCP and UDP sockets for network I/O.  The sockets are event
 * sources in the task system.
 *
 * When I/O completes, a completion event for the socket is posted to the
 * event queue of the task which requested the I/O.
 *
 * \li MP:
 *	The module ensures appropriate synchronization of data structures it
 *	creates and manipulates.
 *	Clients of this module must not be holding a socket's task's lock when
 *	making a call that affects that socket.  Failure to follow this rule
 *	can result in deadlock.
 *	The caller must ensure that isc_socketmgr_destroy() is called only
 *	once for a given manager.
 *
 * \li Reliability:
 *	No anticipated impact.
 *
 * \li Resources:
 *	TBS
 *
 * \li Security:
 *	No anticipated impact.
 *
 * \li Standards:
 *	None.
