server won't respond...
I am connecting a client to a server via the loopback. The client is well tested and sends/recieves normally. The server acknowledges the connection (as does the client), but when I send the first packet to the server, it just sits there, dutifully awaiting data. No recieve error, and no 0 recieves. The client assures "Waiting for reply...", but that's it. When I kill the server, the client promtly notifies that the connection was lost. Any ideas?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Ok, wierd. when I close the client's socket directly after sending the data, the server acknowledges the reciept. Paradoxically, I cannot recieve the server's response now, since the client was using that socket for recieving too. No problem, just'll use another, but the thing that doesn't make sense is that the client connects to external servers without shutting down after the send (I do it after the recieve). Why is my server different? because it too is using a single socket?? Not sure, there...
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
got it
Thanks sebastiani

Glad to be of service.
where did you learn the socket programming? I have wanted to learn itr for a long time, and what compiler are you using?

The Winsock Faq has some really good examples. There use to be a site called Beej's that had all kinds of fun hacks, but it seems to have dissapeared. You can use the compiler you're using, just #include <winsock.h> in your projects and link to the static library, "libwsock32.a". To do that, go to Project->Project Options, and in the box labeled "Further object files or linker options...", type this line, verbatim:
-lwsock32
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
THANKS MAN!
I have been looking for that stuff for a log time, and you managed o tell me in less thatn a paragraph...
thanks.

Thanks, Prelude. I'll update my bookmark.
You will be pleasantly surprised by the simplicity of it all.any good books to suplement this? i think i am in way over my head...

When all else fails, read the instructions.

Dang. I have already created a simple telnet program that shows all telnet input to the cout, and it is written to a file. Now, where can i find out how to make threads so that i can make multiple connections to the program?
