tanx for reply, but it seems i couldn't explain the situation,i know how udp works, the reason i compared it with tcp is that i want to know, when data comes to the udp server/client does it buffer data or it just returns it? cause in TCP case data is first buffered, either in sending side or receiving side, but in UDP its not buffered in sending side, will it be buffered in receiving side?

You have asked a variation of the same question five times in under two weeks. If you have a specific problem with your current code, please post it with a clear description of your intent vs. the result.	[reply]

how do we check if the buffer contains data, so that we could read from it What type of application are you trying to capture/steal data from? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."	[reply]

You question isn't very clear. If you want to check if you can read some data from the socket you can use select or IO::Select.	[reply]
