Data available on socket?

[Jan Danielsson]

Hello all,

How do I find out if a blocking socket has data available [for
reading] on it?

I assume I could do something like this:

tmp = self.read(1, socket.MSG_PEEK)
if len(tmp) > 0:
# Data available

But is there a better way? A call which specifically checks if data
is available?

Hello,

You might want to use select.select.
See http://effbot.org/librarybook/select.htm for an example with sockets.
