4.2 Declaring the exported function
There are two ways to declare a function in a DLL: one for the 4.1-section example, plus __declspec (dllexport) in the function declaration, which is no longer illustrated here; another way is to use the module definition (. def) file declaration,. The DEF file provides the linker with information about the exported, attributes, and other aspects of the linked program.
The following code shows how to do the same.

Chapter 1 Why dynamic link library (DLL)
When you mention a DLL, you will not be unfamiliar. in Windows, there are a large number of files suffixed with DLL, which are an important guarantee to ensure the normal operation and maintenance of Windows. (For example, the Win95 System directory contains more than 500 DLL fi

Section 2nd describes how to provide the Add function interface using the static Link Library. Next we will look at how to use the dynamic link library to implement the Add function with the same function.

Why DLL
Let's take a look at the differences between the static library and the DLL.
Executable File generation (link phase): the former is very slow (because all symbol definitions in the library need to be linked to the EXE file ), the latter is very fast (because the latter is unsigned by the link's import and storage file)The size of the executable file: the former is very large, and the latter is very
