Re: [Cpptool-develop] Encountered a problem with Windows-DLL concept of the parser.

[Baptiste L. <gai...@fr...>]

This should work correctly if all applications are using the same run-time
library (in C++/Code Generation) dll. If that was not the case, neither the
vc6 plug-in nor cppunit would work and creating MFC extension DLL would be
impossible.

Using pointer across DLL is fine as long as they have the same memory model.
For example, even if no pointer was passed, a exception can not cross DLL
boundary if the application is 'release' and the dll 'debug' because they do
not have the same stack structure.

Linking the libraries directly directly in the plug-in code would work, and
it might be easier for deployment (just one dll to copy). On the other hand,
dll are faster to test (no extra link step).
