I just need to get the IP address of the machine that the program is running on, within C. I'm aware of the

gethostbyname(argv[1]);

Function, but this needs the host name. Basically I just need it to spit out the IP of the computer the program is running on. Of course I know one can easily run a program like ifconfig, but I want to quickly find the IP so I have it within my program, using a quick system call.

Thanks!

You need to use the gethostname() system call.
