Question

I’m trying to obtain the device’s IP Address with no luck.
All the methods I could find on Google and SO doesn’t work.

For example, most recent answer

https://stackoverflow.com/a/14084031/975959

I’m getting compilation errors:

Use of undeclared identifier ‘getifaddrs’

and

Use of undeclared identifier ‘freeifaddrs’

The I’m having the same problem as the one who asked this question.
gethostname() return *****s-iPhone and using it in this line struct hostent *host = gethostbyname(...) returns NULL

I’m working on the device, but I guess compilation errors has nothing to do with it.

Any thoughts?

P.S.

If it matters, I’m using Base SDK 6.0, deployment target 5.0

You have to include those

#include <sys/types.h>
#include <sys/socket.h>
#include <ifaddrs.h>
#include <net/if.h>
#include <netdb.h>
