/**
* @defgroup globus_xio_tcp_driver_instance Opening/Closing
* @ingroup globus_xio_tcp_driver
*
* An XIO handle with the tcp driver can be created with either
* @ref globus_xio_handle_create() or @ref globus_xio_server_register_accept().
*
* If the handle is created with @ref globus_xio_server_register_accept(),
* the @ref globus_xio_register_open() call does nothing more than initialize
* the internal handle with the accepted socket.
*
* If the handle is created with @ref globus_xio_handle_create(), and
* there is no handle set on the attr passed to the
* @ref globus_xio_register_open() call, it performs the equivalent of an
* asynchronous connect() call. In this case, the contact string must contain
* a host name and service/port. Both the hostname and port number can be
* numeric or symbolic (eg: some.webserver.com:80 or 214.123.12.1:http).
* If the hostname is symbolic and it resolves to multiple ip addresses, each
* one will be attempted in succession, until the connect is successful or
* there are no more addresses.
*
* When the XIO handle is closed, the tcp driver will destroy its internal
* resources and close the socket (unless this socket was set on an attr).
* Any write data pending in system buffers will be sent unless the linger
* option has been set. Any remaining data in recv buffers will be discarded
* and (on some systems) a connection reset sent to the peer.
*/
/**
* @defgroup globus_xio_tcp_driver_io Reading/Writing
* @ingroup globus_xio_tcp_driver
*
* Both the @ref globus_xio_register_read() and
* @ref globus_xio_register_write() calls follow similar semantics as described
* below.
*
* If the waitforbytes parameter is greater than zero, the io will happen
* asynchronously and be completed when at least waitforbytes has been
* read/written.
*
* If the waitforbytes parameter is equal to zero, one of the following
* alternative behaviors occur:
*
* If the length of the buffer is > 0 the read or write happens synchronously.
* If the user is using one of the blocking xio calls, no internal callback
* will occur.
*
* If the length of the buffer is also 0, the call behaves like an asynchronous
* notification of data ready to be either read or written. ie, an
* asynchronous select().
*
* In any case, when an error or EOF occurs before the waitforbytes request
* has been met, the outgoing nbytes is set to the amount of data actually
* read/written before the error or EOF occurred.
*/
/**
* @defgroup globus_xio_tcp_driver_server Server
* @ingroup globus_xio_tcp_driver
*
* @ref globus_xio_server_create() causes a tcp listener socket to be created
* and listened upon. @ref globus_xio_server_register_accept() performs an
* asynchronous accept(). @ref globus_xio_server_register_close() cleans up
* the internal resources associated with the tcp server and calls close() on
* the listener socket (unless the socket was set on the server via the attr)
*
* All accepted handles inherit all tcp specific attributes set in the attr to
* @ref globus_xio_server_create(), but can be overridden with the attr to
* @ref globus_xio_register_open().
*/
/**
* @defgroup globus_xio_tcp_driver_envs Env Variables
* @ingroup globus_xio_tcp_driver
*
* The tcp driver uses the following environment variables
* - GLOBUS_HOSTNAME Used when setting the hostname in the contact string
* - GLOBUS_TCP_PORT_RANGE Used to restrict anonymous listener ports
* ex: GLOBUS_TCP_PORT_RANGE=4000,4100
* - GLOBUS_TCP_PORT_RANGE_STATE_FILE Used in conjunction with
* GLOBUS_TCP_PORT_RANGE to maintain last used port among many
* applications making use of the same port range. That last port + 1
* will be used as a starting point within the specified tcp port range
* instead of always starting at the beginning. This is really only
* necessary when a machine is behind a stateful firewall which is holding
* a port in a different state than the application's machine.
* See bugzilla.globus.org, bug 1851 for more info.
* ex: GLOBUS_TCP_PORT_RANGE_STATE_FILE=/tmp/port_state
* (file will be created if it does not exist)
* - GLOBUS_TCP_SOURCE_RANGE Used to restrict local ports used in a connection
* - GLOBUS_XIO_TCP_DEBUG Available if using a debug build. See globus_debug.h
* for format. The TCP driver defines the levels TRACE for all function
* call tracing and INFO for write buffer sizes
* - GLOBUS_XIO_SYSTEM_DEBUG Available if using a debug build. See
* globus_debug.h for format. The TCP driver uses globus_xio_system
* (along with the File and UDP drivers) which defines the following
* levels: TRACE for all function call tracing, DATA for data read and
* written counts, INFO for some special events, and RAW which dumps the
* raw buffers actually read or written. This can contain binary data,
* so be careful when you enable it.
