macOS Get the host name via C/C++ at kernel level

[eddyq]

Is there a way to get the host name while in a KEXT? I can use C++ or C.

I'm sure there's a few ways...

getenv("$HOSTNAME");

might be one way.

char myhost[20];
gethostname(&myhost, sizeof(myhost));

is another...

There may be some more Mac specific API calls to do this as well...

Are you sure these can be called from kernel level? When I try it they are not found.
