hi @all i have an 3d engine running good and now i try to learn network programming to make it multiplayer....it works good, i have server and client funktion working but now i have little question how did i get the own IP adress in an string to show and/or use it ingame (at moment i use 127.0.0.1) i think it works with -> GetHostName() but it didnt work have anybody a simple example how to get it to run? another thing... at the moment i use tpc.. i found a command to disable the needle algo that ,like i understand, turn off waiting for returning tcp ok signal to send the next one -> TCPNODELAY i try it,but my server crash with it is this function good or useless....?! thx for any answer SVEN (sorry for my bad english)

for the needle turn off algo i try this:

BOOL wert_delay=1;

setsockopt (sClient,IPPROTO_TCP,TCP_NODELAY,(LPSTR)wert_delay,sizeof(BOOL));


but my app crashes with this ..whats wrong with it?
(p.s.: for that what i want to do i cant!! use UDP,
i only want to speed up tcp a little bit)

Yeah, nice of them to tell you two different things in the documentation... While the ''option'' you pass to setsockopt is indeed a logical boolean value, sending it a real ''bool'' type variable will cause problems. I offer you the following from MSDN:

quote:

---

To enable a Boolean option, optval points to a nonzero integer. To disable the option optval points to an integer equal to zero. The optlen parameter should be equal to sizeof(int) for Boolean options.

---

So pass in an int that is 1 or 0 instead of a BOOL.

FYI, it's Nagle, not Needle.

Also FYI, disabling Nagle algorithm comes with a hefty warning label, courtesy of Winsock Programmer's FAQ.

ah..aaaah...BOOL..that was my error , thx
(omg...i am so stupid )

it works perfect....
its speeds up my network data transfer
without have to use UDP

and now i found how to get the
own IP as an string

perfect


(i think i have to learn a better english
that will help me understand the documentations)
