send/recv urgdata on tcp application

Hello,

How to send/recv URGENT data on TCP application using socket options.

Thanks in advance,
Srini.

Use MSG_OOB flag while sending.

Eg:

send (sock_fd, data, (data_length), MSG_OOB)

This shud do.

Can't we send without using MSG_OOB. Is it possible to use setsockopt() for sending urgdata.

thanks,
sri.

Using setsockopt u can say how to handle Urg data.

It looks like, u need to send data with URG set only on certain occasions. If you can be a bit clear on what u expect, we can try to come out with some more clear explanations.

Thanks for reply,
What I need is "Is it possible to send URGDATA not using MSG_OOB. Is there any mechanism. I am implementing tcp/ip multiple client server implementation.
I am capturing all packets using etheral sniffer.

Thanks!
