RE: Odd Sockets Problem...

["York, Albert" <albert.york@xxxxxxxxxxxxxx>]

Do you have control over what the server is sending?

If so, I would add an "end of line" code to indicate that you have received
the entire response. 

For example:

Response1aResponse1bDONE

Other than that you could add a timeout on the SELECT() statement.

It sounds like the server is not sending everything at once. So the time
between responses could be dependent upon how busy the server is.

        Subject:        Odd Sockets Problem...

        I'm playing around with sockets again and having some odd
        responses from the server I'm speaking with.

        Sometimes when I send a request, I get a response, but not
        all of it...

        So it should be:

        Me: Command1
        Server: Response1a Response1b Response1....
        Me Command2
        Server Response2

        In some cases this works, in other cases it doesn't.
         Sometimes I get:

        Me: Command1
        Server: Response1a
        Me: Command2
        Server: Response1b

        And from there the responses are all messed up and my app
        gets "confused" as to what it should be doing...  

        I am using select() before each read().  I've debugged it
        and in the cases where I don't get "all the responses" on
        one read, if I do another read it gets the rest just fine.

        But, two problems with that:

        1.  I never know if I got "all reponses" or not.. there
        could be 1 or more responses.
        2.  I don't know ahead of time the responses I should get.
         

        Any ideas why it wouldn't be sending the entire response in
        one read() all the time, only part of the time?  I check
        RC, and the buffer length is much larger than the data
        returned.  Wacky stuff.  :)
