-A brief overview on how to use these flags follows.
+\func{}{wxSocketBase}{\void}
-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.
+Default constructor. Don't use it directly; instead, use
+\helpref{wxSocketClient}{wxsocketclient} to construct a socket client, or
+\helpref{wxSocketServer}{wxsocketserver} to construct a socket server.
-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.
+\membersection{wxSocketBase::\destruct{wxSocketBase}}\label{wxsocketbasedestruct}
-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.
+\func{}{\destruct{wxSocketBase}}{\void}
-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.
+Destructor. Do not destroy a socket using the delete operator directly;
+use \helpref{Destroy}{wxsocketbasedestroy} instead. Also, do not create
+socket objects in the stack.

+\membersection{wxSocketBase::Callback}\label{wxsocketbasecallback}
-{\bf wxSOCKET\_NONE} will try to read at least SOME data, no matter how much.
+\func{wxSocketBase::wxSockCbk}{Callback}{\param{wxSocketBase::wxSockCbk}{ callback}}
-{\bf wxSOCKET\_NOWAIT} will always return immediately, even if it cannot
-read or write ANY data.
+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:
-{\bf wxSOCKET\_WAITALL} will only return when it has read or written ALL
-the data.
+\begin{verbatim}
+void SocketCallback(wxSocketBase& sock, wxSocketNotify evt, char *cdata);
+\end{verbatim}
-{\bf wxSOCKET\_BLOCK} has nothing to do with the previous flags and
-it controls whether the GUI blocks.
+The first parameter is a reference to the socket object in which the
+event occured. The second parameter tells you which event occured.
+(See \helpref{wxSocket events}{wxsocketbase}). The third parameter
+is the user data you specified using \helpref{CallbackData}{wxsocketbasecallbackdata}.
+
+Note that events are preferred over callbacks where possible.

-This function sets the default socket timeout in seconds. This timeout
-applies to all IO calls, and also to the \helpref{Wait}{wxsocketbasewait}
-family of functions if you don't specify a wait interval. Initially, the
-default is set to 10 minutes.
+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. This means that you don't need to do it yourself, unless you
+explicitly want to disable further operation.
+
+\wxheading{Remark/Warning}
+
+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.

+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
