For example: Copy __declspec(dllexport) void __cdecl Function1(void); To export all of the public data members and member functions in a class, the keyword must appear to the left of the class

Leaving out these four lines might cause your DLL to compile or link incorrectly or cause an error when the client application links to the DLL.When building the DLL, the linker Advantages An exported C++ class can be used via an abstract interface, with any C++ compiler. Or maybe this is from the perspective of the DLL, after it has been constructed, and means that the DLL will export to the application that will use the DLL?

That DLL should be used in a project built with Embarcadero C++Builder XE6(former: Borland c++). Here is an example of how a client's C code might look like: #include "XyzLibrary.h" ... /* Create Xyz instance. */ XYZHANDLE hXyz = GetXyz(); if(hXyz) { /* Call Xyz.Foo method.

When you do this, the linker will provide the system with the information that is required to load the DLL and resolve the exported DLL function locations at load time. The AutoClosePtr template is the simplest implementation of a smart pointer that calls an arbitrary method of a class to destroy an instance instead of operator delete.
