-\membersection{wxSocketBase::wxSocketBase}
+A brief note on how to use these events:
+
+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 succesfully (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. Also, this event will be issued if
+a connection request fails.

-\wxheading{Parameters}
+You can setup a callback function to be called when an event occurs.
+The function will be called only for those events for which notification
+has been enabled with \helpref{Notify}{wxsocketbasenotify} and 
+\helpref{SetNotify}{wxsocketbasesetnotify}. The prototype of the
+callback must be as follows:

 
 

-\docparam{buffer}{Buffer where to put read data.}
+\begin{verbatim}
+void SocketCallback(wxSocketBase& sock, wxSocketNotify evt, char *cdata);
+\end{verbatim}

 
 

-\docparam{nbytes}{Number of bytes.}
+The first parameter is a reference to the socket object in which the
+event occurred. The second parameter tells you which event occurred.
+(See \helpref{wxSocket events}{wxsocketbase}). The third parameter
+is the user data you specified using \helpref{CallbackData}{wxsocketbasecallbackdata}.

 
 \wxheading{Return value}
 
 
 \wxheading{Return value}
 

-Returns a reference to the current object.
+A pointer to the previous callback.

 
 \wxheading{Remark/Warning}
 
 
 \wxheading{Remark/Warning}
 

-By default, Read uses an internal asynchronous manager: it will send data when
-the socket requests them. It is particularly interesting when you enter a long
-data transfer (e.g. a big file, an image, ...). But it is also buggy when you
-simply discuss with the peer using user data. In this case, wxSocket prepares
-itself to send data (Write wait for them to be sent) and during a GUI refresh
-the user enters new data, which involves a new Read call though the previous
-isn't finished. Well, in most cases it can work but it might fail too.
-So I advise you to use the SPEED flag, which disables the asynchronous manager,
-when you just want to discuss with the peer.
-
-This remark is also valid for all IO call.
+Note that callbacks are now deprecated and unsupported, and they remain
+for backwards compatibility only. Use events instead.

-By default, Write uses an internal asynchronous manager: it will send data when

+\func{void}{Close}{\void}

 
 

-This function writes a buffer of {\it nbytes} bytes from the socket. But it
-writes a short header before so that ReadMsg can alloc the right size for
-the buffer. So a buffer sent with WriteMsg {\bf must} be read with ReadMsg.
+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.

 
 

-\wxheading{Parameters}
+\wxheading{Remark/Warning}

 
 

-\docparam{buffer}{Buffer where to put data peeked.}
+Although Close immediately disables events for the socket, it is possible
+that event messages may be waiting in the application's event queue. The

-Returns a reference to the current object.
+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.

-\helpref{wxSocketBase}{wxsocketbase}
+Use SetFlags to customize IO operation for this socket.
+The {\it flags} parameter may be a combination of flags ORed toghether.
+The following flags can be used:

 
 

-\wxheading{Include files}
+\twocolwidtha{7cm}
+\begin{twocollist}\itemsep=0pt
+\twocolitem{{\bf wxSOCKET\_NONE}}{Normal functionality.}
+\twocolitem{{\bf wxSOCKET\_NOWAIT}}{Read/write as much data as possible and return immediately.}
+\twocolitem{{\bf wxSOCKET\_WAITALL}}{Wait for all required data to be read/written unless an error occurs.}
+\twocolitem{{\bf wxSOCKET\_BLOCK}}{Block the GUI (do not yield) while reading/writing data.}
+\end{twocollist}

 
 

-<wx/socket.h>
+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.
+
+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.
