What for are the __declspec and __cdecl operators needed ???

Answer 1

__declspec
This is a Microsoft specific extension to the C++ language which allows you to attribute a type or function with storage class information.
__cdecl
__cdecl is the default calling convention for C and C++ programs. Because the stack is cleaned up by the caller, it can do vararg functions. The __cdecl calling convention creates larger executables than __stdcall, because it requires each function call to include stack cleanup code. The following list shows the implementation of this calling convention.
Hope you get the correct answer 😉💚

Answer 5

Microsoft introduced __export in the 16-bit compiler version of Visual C++ to allow the compiler to generate the export names automatically and place them in a .lib file. This .lib file can then be used just like a static .lib to link with a DLL.
In newer compiler versions, you can export data, functions, classes, or class member functions from a DLL using the __declspec(dllexport) keyword. __declspec(dllexport) adds the export directive to the object file so you do not need to use a .def file.
