Need help to obtain NIC IP and MAC in C

Hi all.

I want to obtain the IP address and MAC address of the local NIC. How to write the code in C? or any header file and library can be used?

Thanks.

getaddrinfo or gethostbyname on the local host (obtained by gethostname) should return all the IP addresses of the local host (127.0.0.1 and another).

thank you. Which header file or library support "getaddrinfo"?

I am using Mingw 3.4.2 (Dev-C++). Thanks.

ws2tcpip.h

For future reference, if you install something like msys you can use grep to search files for a specific function. Or you can use google.

gethostbyname doesn't always work. If you want the sure-fire way to do it, look at the code for ifconfig in BusyBox.
