Hello,

I will have to build my application with a different compiler at some point.
The secure functions like sprintf_s are a nice feature of the visual c++
compiler. But they will probably not be supported on the target platform. If
I had the possibility to #define a macro which uses sprintf_s if the visual
c++ compiler is used and uses the standard sprintf if a different compiler is
used I would not have to switch off the deprecated warnings.
Can I define a macro with optional arguments as sprintf resp. sprintf_s use?

Thanks for your suggestions,

Fabian

Yes, VC++ supports variadic macros:

Depending on your exact situation, you should do it another way :
Write your code using printf, and when compiling with Visual C++
#define, _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES = 1

How can I find out automatically whether I am compiling with Visual C++? If
I try it with #ifdef _MSVC_ Visual Studio tells me (by greying out the
following code) that _MSVC_ is not defined.

Thanks,

Fabian

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
