how to get hostname and IP address of a machine

Hi,

I want to get the hostname and the ip address of the machine in C on both windows and linux environments. Are there any functions in C which will give me this information?

Thanks,
Chandana.

gethostname(), gethostbyaddr(), gethostbyname().

Thanks for the reply.
Can you give me some sample code which uses this gethostname(). I am trying to call gethostname() from the main function, but I am getting "segmentation fault" error.

Post your code that is giving you the seg fault.

As a first guess I'd say that you don't have a big enough buffer for the hostname which is stored in the first argument of gethostname().
