There should be no problem with calling the LWIP C functions from C++. The only thing you have to ensure is that function prototypes are declared to be external C functions.

The easiest way to do this is to wrap the include for the LWIP files in an extern "C" decleration, e.g.:

extern "C" {# include "lwip/sys.h"# include "lwip/netif.h"# include "lwip/sockets.h"

};

Other than that, everything should work fine.
