Implicit declaration of function 'ether_ntoa' is invalid in C99
ios, objective-c, xcode
Solution
As I read it, the error message isn't claiming that the function is missing, only that you don't include its declaration. (I don't know that it exists, only that the message has a different complaint.)
In case it helps, `man ether_ntoa` tells me:
#include <sys/types.h>
#include <sys/socket.h>
#include <net/ethernet.h>
Problem
It's part of a series of functions that retrieve IP & Mac addresses from the phone. ``` strcpy(temp, (char *)ether_ntoa((const struct ether_addr *)LLADDR(sdl))); ``` EDIT: No equivalent function needed, there were just a few missing headers. EDIT: Added cast to LLADDR(sdl)
