you use C++ files, but you tag your question as everything but C++. Can you edit the tags? and the error means that you're missing some includes. Maybe the C++ headers miss the `extern "C"` wrappers? Can you show `P2PLib.h` ? – Jean-François Fabre Sep 28 '16 at 13:37

You don't have the definition of this function in your header. Check your header and/or spelling. Also don't post images of code, post the code as text! – Eugene Sh. Sep 28 '16 at 13:52
hi Jean-François Fabre, My "P2PLib.h" File code is http://paste.ofcode.org/BDSXSP3e7yxg4bJEVP2DQk – Varinder Singh iPhone Dev Sep 28 '16 at 13:53
Have you tried to actually compile it? It could be just the IDE false alarm. – Eugene Sh. Sep 28 '16 at 13:57

I am facing same Error. – Mss iOS Sep 28 '16 at 14:04
It might be something to do with the `P2P_API` macros in the header file, which seem to be defined as appropriate for MS Windows unless the `__linux` macro is defined. Is there a version of the header file that is more appropriate for iOS? – Ian Abbott Sep 28 '16 at 16:50
it could be the compiler is not seeing both parameter to the function as `char *` – user3629249 Sep 30 '16 at 00:19
