    Is it possible to read & modify TCP header using C. Also I want a
    sample C code for this. Please reply immediately.

      Yes if something has already captured the header and put it somewhere
      you C code can access. How to interface to the network though is
      implementation specific so you will have to ask in a group dedicated to
      your system.

      In that case I suggest using Google to search for some.

      Usenet is not an immediate medium. Things take time to propagate,
      generally people are not paid to use it so it is when they have the time
      and inclination, and even if someone replies immediately it might take a
      long time to reach you.

      If you want immediate response you have to pay hard cash for it in general.

            Yassuh, right away. Your want is my command. No. The C standard
            never mentions a TCP header.

              And if you want *any* reply here, immediate or not, don't use silly
              abbreviations like "abt" for "about", and use standard capitalzation
              and punctuation. This isn't a chat room or a text messaging system.

              Also, read <http://cfaj.freeshell. org/google/>.
