in c++ what function will return your IP address? I have searched for it
but no luck. I figured you guys would know it off the top of your

If you’re using windows, you can get your IP address using WinSock. You
can’t get the IP address in “C/C++”. You’ll have to use a library.
wVersionRequested = MAKEWORD( 2, 0 );
if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
if( gethostname ( name, sizeof(name)) == 0)
if((hostinfo = gethostbyname(name)) != NULL)
ip = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list);
don’t forget to link with Wsock32.lib
if u use apex’s code ( into VC6.0 ), and u need #include <windows.h>
u must put #include <winsock2.h> before windows include. Otherwise
the compiler found data types repeated. ;)
I have another question…. :)
I am using WinSock.
When i call: recv() it waits at that line until it is sent something. Is
there a way i can set the function to time out if nothing is sent after
a few secs? I am writing a simple chat program..and i need it to check
if something was recieved..and if it didnt then just contenue with the
//recieve text //i dont need it to wait here until it is sent something
Using WSAAsyncSelect u can recive a message to a window procedure when u
get some data, or other network event, about u socket. Try to use it !!!
or have a look at select() …
