/**
 * @file Ecore_Con.h
 * @brief Sockets functions.
 *
 * The Ecore Connection Library ( @c Ecore_Con ) provides simple mechanisms
 * for communications between programs using reliable sockets.  It saves
 * the programmer from having to worry about file descripters and waiting
 * for incoming connections.
 *
 * There are two main objects in the @c Ecore_Con library: the @c
 * Ecore_Con_Server and the @c Ecore_Con_Client.
 *
 * The @c Ecore_Con_Server represents a server to connect to.  It is
 * represents a server that can be connected to.  It is used regardless
 * of whether the program is acting as a server or client itself.
 *
 * To create a listening server, call @c ecore_con_server_add().
 *
 * To connect to a server, call @c ecore_Con_server_connect().  Data can
 * then be sent to the server using the @c ecore_con_server_send().
 * 
 * Whenever a client connection is made to an @c Ecore_Con_Server, a
 * @c ECORE_CON_CLIENT_ADD event is emitted.  Any event callbacks that are
 * called receive a @c Ecore_Con_Client object, which represents a
 * connection that that particular client.
 *
 * Functions are described in the following groupings:
 * @li @ref Ecore_Con_Lib_Group
 * @li @ref Ecore_Con_Server_Group
 * @li @ref Ecore_Con_Client_Group
