BNCS Chatgate Event Handler (VB 6.0)

I thought that it does. But then again I may be wrong.

Doesn't that require multithreading?

No.  BinaryChat uses overlapped I/O and runs everything (the GUI included) in a single thread, and supports any number of bot connections per process.

I don't understand how that's different from select().

It's completely different.  If you read the Winsock documentation, select is severely crippled under Win32.

Perhaps I'm writing in Python...
What exactly does overlapped I/O do though? select() for me returns a list of channels that are readable at the moment and can do non-blocking reads, I just set the select() value to 5 ms so it has a little waiting time.

Whether you are using Python or not doesn't matter if it's on Win32,  which your earlier comments suggested.

Overlapped I/O lets the system perform the I/O operations in dedicated worker threads, returning the result to you when it's completed.  In Windows NT, for the most part this is what goes on already, it's just that for example ReadFile by default waits for the I/O operation to complete.

When used with sockets, you eliminate extra copying of data, thus increasing performance.  Additionally, it removes the 64-socket limitation; you can have any number of pending overlapped operations per thread.
