how to make a non-blockin recv from perl socket

Question

I make a recv call on a TCP socket and it tured out to be that the recv call is a blocking one even though the socket itself has set to be in non-blocking mode. So my question is just as simple as: how to implement a non-blocking recv on a perl socket? thanks in advance.

Answer 1

Try passing the MSG_DONTWAIT flag to your recv call.

Answer 3

Use the 4 argument version of select to check whether there is input on the socket before you try to recv from it.

Answer 4

If your looking for a simpler interface to select mentioned by mobrule IO::Select provides an OO interface to it.
