+| 0x01
+| POLLIN
+| Both
+| Can recv() data from socket without blocking. For listen sockets, this means you can accept() a connection without blocking.
+|-
+| 0x02
+| POLLPRI
+| Both
+| There is OOB data ready to recv(). Appears that recv()'ing without OOB flag still reads OOB data?
+|-
+| 0x04
+| ???
+| ???
+| Have never seen this flag. Could possibly be POLLHUP (need to test).
+|-
+| 0x08
+| ???
+| ???
+| This flag is almost always set when requested.
+|-
+| 0x10
+| POLLOUT
+| Both
+| Can send() data to socket without blocking. For a non-blocking connect(), this means the connection has completed (need to test).
+|-
+| 0x20
+| POLLNVAL
+| Out
+| Invalid socket handle. This is set if you use fd=-1, which is non-standard behavior.
+|-
+| ???
+| POLLERR
+| Out
+| Socket error.
+|-
+| ???
+| POLLHUP
+| Out
+| Socket has been disconnected.
