+\end{twocollist}
+
+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 delayed connection request fails.

+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.
