使用在 VS 2019 环境中开发的 DLL 在尝试启动 VS 2008 环境中内置的 exe 时触发崩溃

Question

I have a DLL that is developed in VS 2019 environment.

It has following Interface.

bool Initialize();
{
     // Do nothing
}

Interface declaration in DLL

extern "C" CDACVS19LIBRARY_API bool Initialize();

I uses the above Interface in one of the console exe created in VS2008 Environment as follows.

Initialize();

When I invoke this interface it is throwing below error

Run-time Check Failure #2 - Stack around the variable 'oss_' was corrupted.

What is wrong in the above code/approach?

There is something wrong about using a dll built in VS2019 environment in an exe developed in VS 2008 environment as we are using something built in later version in older version.

Is it not possible to do so? If possible, where I am not right in following the above approach?

If I use the same dll in a console exe built in 2019 environment, everything works just fine.

EDIT : Edited to make Interface declaration and definition proper.

Answer 1

First of all your declarations and defintions must match exactly.

Secondly,if you want your DLL to be used by any program (no matter which compiler\language used) you must not use anything that could change by compilerversions in the DLL-interface. This means restrict your DLL-interface to C-compatible functionalities,don't expose any STL-stuff or templates and do not rely on default calling-conventions for functions (decorate them as extern "C" or _cdecl). Write your interfaces as if your writing for C. Inside your DLL you do whatever you want.
