Your question is so vague as to be almost meaningless. For example,
what is the "we"? Are you talking about a program that might want to
monitor whether it is dropping UDP packets out of its own buffer? Or
are you talking about some kind of monitoring device looking in at a
program?

And what do you mean by "polling"? That term has many different
meanings.

See his other thread "UDP packets dropped" for the context. I don't
understand why he started a new thread rather than simply continuing in
the original thread.

Here i am referring to to a program( software, some API, some system
call, some function at the application level or at the kernel level
which will tell me when buffer is overflowing and packets are being
dropped )
I dont mean a monitoring device/ hardware for this purpose. Well, if
you know of any monitoring device please let me know. I will be more
than happy to get any relevant information.

By polling I mean using system call like poll or select in Unix
Networking Programming

Sorry for bothering you by writing two messages. I wrote the long one
first and after submitting I realised I might have written it
unnecessarily long so I wrote the next message which was concise.
As I am using Google Groups I did not I could relate the two messages
as one.

Thanks

Your other post is very good. Don't worry about the length, as long as
it's focused and contains important information.
