 \section{\class{wxSocketBase}}\label{wxsocketbase}
 
+wxSocketBase is the base class for all socket-related objects, and it
+defines all basic IO functionality.
+
+Note: (Workaround for implementation limitation for wxWidgets up to 2.5.x)
+If you want to use sockets or derived classes such as wxFTP in a secondary thread,
+call wxSocketBase::Initialize() (undocumented) from the main thread before creating 
+any sockets - in wxApp::OnInit for example. 
+See http://wiki.wxwidgets.org/wiki.pl?WxSocket or
+http://www.litwindow.com/knowhow/knowhow.html for more details.

 A brief note on how to use these events:
 
-The {\bf wxSOCKET\_INPUT} event will be issued when the incoming queue
-was empty and new data arrives, but NOT if new data arrives when there
-was data waiting in the incoming queue.
-
-The {\bf wxSOCKET\_OUTPUT} event is issued when a socket is first connected
-with Connect or accepted with Accept, and then, only after an output operation
-fails because the output buffer was full, and buffer space becomes available
-again.
-
-The {\bf wxSOCKET\_CONNECTION} event is issued when a connection request
-completes (client) or when a new connection arrives at the pending
-connections queue (server).
+The {\bf wxSOCKET\_INPUT} event will be issued whenever there is data
+available for reading. This will be the case if the input queue was
+empty and new data arrives, or if the application has read some data
+yet there is still more data available. This means that the application
+does not need to read all available data in response to a 
+{\bf wxSOCKET\_INPUT} event, as more events will be produced as
+necessary.
+
+The {\bf wxSOCKET\_OUTPUT} event is issued when a socket is first
+connected with \helpref{Connect}{wxsocketclientconnect} or accepted
+with \helpref{Accept}{wxsocketserveraccept}. After that, new
+events will be generated only after an output operation fails
+with {\bf wxSOCKET\_WOULDBLOCK} and buffer space becomes available
+again. This means that the application should assume that it
+can write data to the socket until an {\bf wxSOCKET\_WOULDBLOCK} 
+error occurs; after this, whenever the socket becomes writable
+again the application will be notified with another 
+{\bf wxSOCKET\_OUTPUT} event.
+
+The {\bf wxSOCKET\_CONNECTION} event is issued when a delayed connection
+request completes successfully (client) or when a new connection arrives
+at the incoming queue (server).
 
 The {\bf wxSOCKET\_LOST} event is issued when a close indication is
 received for the socket. This means that the connection broke down or
-that it was closed by the peer.
+that it was closed by the peer. Also, this event will be issued if
+a connection request fails.

-\func{void}{SetFlags}{\param{wxSocketBase::wxSockFlags}{ flags}}
+This function shuts down the socket, disabling further transmission and
+reception of data; it also disables events for the socket and frees the
+associated system resources. Upon socket destruction, Close is automatically
+called, so in most cases you won't need to do it yourself, unless you
+explicitly want to shut down the socket, typically to notify the peer
+that you are closing the connection.

-\twocolitem{{\bf wxSOCKET\_BLOCK}}{Block the GUI (do not wxYield) while reading/writing data.}
-\end{twocollist}
+\wxheading{Remark/Warning}
 
-A brief overview on how to use these flags follows.
+Although Close immediately disables events for the socket, it is possible
+that event messages may be waiting in the application's event queue. The
+application must therefore be prepared to handle socket event messages
+even after calling Close.
 
-If no flag is specified (this is the same as {\bf wxSOCKET\_NONE}),
-IO calls will return after some data has been read or written, even
-when the transfer might not be complete. This is the same as issuing
-exactly one blocking low-level call to recv() or send(). Note that
-blocking here refers to when the function returns, not to whether
-the GUI blocks during this time.
+%
+% Destroy
+%
+\membersection{wxSocketBase::Destroy}\label{wxsocketbasedestroy}
 
-If {\bf wxSOCKET\_NOWAIT} is specified, IO calls will return immediately.
-Read operations will retrieve only available data. Write operations will
-write as much data as possible, depending on how much space is available
-in the output buffer. This is the same as issuing exactly one nonblocking
-low-level call to recv() or send(). Note that nonblocking here refers to
-when the function returns, not to whether the GUI blocks during this time.
+\func{bool}{Destroy}{\void}
 
-If {\bf wxSOCKET\_WAITALL} is specified, IO calls won't return until ALL
-the data has been read or written (or until an error occurs), blocking if
-necessary, and issuing several low level calls if necessary. This is the
-same as having a loop which makes as many blocking low-level calls to
-recv() or send() as needed so as to transfer all the data. Note that
-"blocking" here refers to when the function returns, not to whether
-the GUI blocks during this time.
+Destroys the socket safely. Use this function instead of the delete operator,
+since otherwise socket events could reach the application even after the
+socket has been destroyed. To prevent this problem, this function appends
+the wxSocket to a list of object to be deleted on idle time, after all
+events have been processed. For the same reason, you should avoid creating
+socket objects in the stack.
 
-The {\bf wxSOCKET\_BLOCK} controls whether the GUI blocks during IO
-operations. If this flag is not used, then the application must take
-extra care to avoid unwanted reentrance. 
+Destroy calls \helpref{Close}{wxsocketbaseclose} automatically.
 
-So:
+\wxheading{Return value}
 
-{\bf wxSOCKET\_NONE} will try to read SOME data, no matter how much.
+Always true.
 
-{\bf wxSOCKET\_NOWAIT} will always return immediately, even if it cannot
-read or write ANY data.
+%
+% Discard
+%
+\membersection{wxSocketBase::Discard}\label{wxsocketbasediscard}
 
-{\bf wxSOCKET\_WAITALL} will only return when it has read or written ALL
-the data.
+\func{wxSocketBase\&}{Discard}{\void}
 
-{\bf wxSOCKET\_BLOCK} has nothing to do with the previous flags and
-it control whether the GUI blocks.
+This function simply deletes all bytes in the incoming queue. This function
+always returns immediately and its operation is not affected by IO flags.
+
+Use \helpref{LastCount}{wxsocketbaselastcount} to verify the number of bytes actually discarded.
+
+If you use \helpref{Error}{wxsocketbaseerror}, it will always return false.

+\twocolitem{{\bf wxSOCKET\_REUSEADDR}}{Allows the use of an in-use port (wxServerSocket only)}
+\end{twocollist}
+
+A brief overview on how to use these flags follows.
+
+If no flag is specified (this is the same as {\bf wxSOCKET\_NONE}),
+IO calls will return after some data has been read or written, even
+when the transfer might not be complete. This is the same as issuing
+exactly one blocking low-level call to recv() or send(). Note
+that {\it blocking} here refers to when the function returns, not
+to whether the GUI blocks during this time.
+
+If {\bf wxSOCKET\_NOWAIT} is specified, IO calls will return immediately.
+Read operations will retrieve only available data. Write operations will
+write as much data as possible, depending on how much space is available
+in the output buffer. This is the same as issuing exactly one nonblocking
+low-level call to recv() or send(). Note that {\it nonblocking} here
+refers to when the function returns, not to whether the GUI blocks during
+this time.
+
+If {\bf wxSOCKET\_WAITALL} is specified, IO calls won't return until ALL
+the data has been read or written (or until an error occurs), blocking if
+necessary, and issuing several low level calls if necessary. This is the
+same as having a loop which makes as many blocking low-level calls to
+recv() or send() as needed so as to transfer all the data. Note
+that {\it blocking} here refers to when the function returns, not
+to whether the GUI blocks during this time.
+
+The {\bf wxSOCKET\_BLOCK} flag controls whether the GUI blocks during
+IO operations. If this flag is specified, the socket will not yield
+during IO calls, so the GUI will remain blocked until the operation
+completes. If it is not used, then the application must take extra
+care to avoid unwanted reentrance.
+
+The {\bf wxSOCKET\_REUSEADDR} flag controls the use of the SO\_REUSEADDR standard
+setsockopt() flag. This flag allows the socket to bind to a port that is already in use.
+This is mostly used on UNIX-based systems to allow rapid starting and stopping of a server - 
+otherwise you may have to wait several minutes for the port to become available.
+wxSOCKET\_REUSEADDR can also be used with socket clients to (re)bind to a particular local port
+for an outgoing connection.
+This option can have surprising platform dependent behavior, so check the documentation for
+your platform's implementation of setsockopt(). Note that on BSD-based systems (e.g. Mac OS X),
+use of wxSOCKET\_REUSEADDR implies SO\_REUSEPORT in addition to SO\_REUSEADDR to be consistent
+with Windows.
+
+So:
+
+{\bf wxSOCKET\_NONE} will try to read at least SOME data, no matter how much.
+
+{\bf wxSOCKET\_NOWAIT} will always return immediately, even if it cannot
+read or write ANY data.
+
+{\bf wxSOCKET\_WAITALL} will only return when it has read or written ALL
+the data.
+
+{\bf wxSOCKET\_BLOCK} has nothing to do with the previous flags and
+it controls whether the GUI blocks.
+
+{\bf wxSOCKET\_REUSEADDR} controls special platform-specific behavior for
+reusing local addresses/ports.
