RE: Weird Sockets Issue...

Do you have a header denoting packet size? If not, do you have a
delimiter?

If the answer is 'No' to both of these questions then it is not possible
to determine the end of the logical data packet. The TCP protocol will
'split' the packets and the only guarantee you have is that they will be
put back in sequence.

Subject: Weird Sockets Issue...

Currently playing around with some client sockets programming and having
a weird issue I never experienced before.

When I run my application one of the response I get back from the server
isn't always complete.

The odd thing is, when I use debug to debug the app, it is always
complete.

I shut off debug, and it doesn't receive the entire response, which
technically would require another read from the socket to get the rest
of the data (actually maybe more than 1 read).

But, I can't just add another read, because if it DOES get all the data,
it hangs on the 2nd read.

I'm using select, but on reads when I get all the data the first time,
the select gives me a timeout error.

Does this make sense at all?  LOL...
