Re: [paho-dev] Using C++ with the Paho C client library

[Roger Light <roger@xxxxxxxxxx>]

Hi Ian,

(1) Make the headers C++ aware internally:

#if defined(__cplusplus)
extern "C" {
#endif

Once the C++ wrapper is written, then C++ programs can use that, and this would become moot.  I have a preference for keeping C++ related stuff out of the C code, but I can see the logic.

This one is pretty trivial, is fully C-conformant, and is fairly common in C libraries these days. It just helps the C++ programmer in not having to remember which headers need to be wrapped. It's not that you're adding any C++ to the header, but rather just making it safe for a C++ app to use directly.

I think that a number of C++ apps might still use the C library directly even if there were a C++ wrapper available.

I'm with Frank on this one. It's trivial to add and does no harm. I've definitely got people using libmosquitto in their C++ code rather than the wrapper, although there may be other reasons for that choice of course.

Regards,

Roger
