+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\_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.

+\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
+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 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
+"blocking" here refers to when the function returns, not to whether
+the GUI blocks during this time.
+
+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. 
+
+So:
+
+{\bf wxSOCKET\_NONE} will try to read 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 control whether the GUI blocks.
