Ok, I've got the C String -> NSString thing down; how would I reverse this process?

My program gets a host name from a field and then works with it. The problem is, getting stuff from a field returns NSString*'s, and I need a character array to pass to gethostbyname(*char). Thanks.

From the NSString documentation in the Foundation reference on Apple's Developer Technical Documentation page:

To get a C string from a string object, use the cString message. This returns a char * in the system's default string encoding, or raises an exception if it can't convert its contents to that encoding. The C string you receive is owned by a temporary object, though, so it will become invalid when automatic deallocation takes place. If you want to get a permanent C string, you must create a buffer and use one of the getCString:... methods to fill it. You can find out how large the buffer needs to be with the cStringLength method.
