Function CheckSockets(timeout_ms)

Checks all connected sockets for activity. If timeout_ms is greater than 0 than it will wait that many milliseconds. If less than 0 it will wait for over 49 days (hint: there is no reason what so ever to set this less than 0).

Returns the number of sockets that have activity (ie. a connection was made or data was sent).

---

Function TCP_SocketReady(socket)

Returns 0 for no activity and non zero for activity. You need to call CheckSockets() at some point before this otherwise it will always return 0.

---

Function UDP_SocketReady(socket)

Returns 0 for no activity and non zero for activity. You need to call CheckSockets() at some point before this otherwise it will always return 0.

If UDP_SocketReady ( 0 ) > 0 Then 
    'Socket has activity so we can do something here
End If
