No 'extern "C"' support in headers

[dosadi]

Hi,

I am attempting to make use of picoTCP in a C++ environment, and I just got eveything to build and noticed that I am getting symbols not being found due to name mangling issues. Normally you would fix this problem to make the C code in picoTCP useable in a C++ environment by enclosing the relevant forward declarations in the header files like this:

extern "C" {
... body of header file ...
} /* extern "C" */

I am going to have to make this type of change myself all through picoTCP's header files to get everything to build, but I thought I'd also open an issue here on GitHub - I couldn't find much about this on a Google search or here in the issues on GH.

Hi @dosadi

In case picoTCP decides not to make this change, or you don't want to wait for them, there's a slightly simpler solution for you : rather than going around all picoTCP headers to put in that extern, you could just use

extern "C" {
#include "foo.h"
#include "bar.h"
} /* extern "C" */

in your c++ files, wherever you're importing a C library.

Works the same way, but may be less work for you :-)

Thanks, that worked! I've never seen that before.
