Freescale USB Stack and C++

weblar — Fri, 16 Nov 2012 14:03:07 GMT

Hi,

I have a C++ application in which I'd like to use the Freescale USB stack, specifically the MSD class.

From previous experience, I've had to decorate my C prototypes with extern "C" in order for them to work in C++, due to the way the linker works.

Will I have to do exactly the same with all routines that make up the USB stack?

Thanks,

Kev

Hello,

with 'extern "C"' you need to mark interfaces you are calling from C++. So whatever you have compiled in C mode, and gets called by C++ code, needs to be marked with that extern "C".

As for the MSD stack, this would only apply to a few routines, I guess. It just depends how you structure your application and the interface to the stack.

Hope this helps,

Erich
