DLL Import and Export Functions
The most complete and up-to-date information on this topic can be found in dllexport, dllimport.
The dllimport and dllexport storage-class modifiers are Microsoft-specific extensions to the C language. These modifiers explicitly define the DLL's interface to its client (the executable file or another DLL). Declaring functions as dllexport eliminates the need for a module-definition (.DEF) file. You can also use the dllimport and dllexport modifiers with data and objects.
The dllimport and dllexport storage-class modifiers must be used with the extended attribute syntax keyword, __declspec, as shown in this example:
#define DllImport __declspec( dllimport ) #define DllExport __declspec( dllexport ) DllExport void func(); DllExport int i = 10; DllExport int j; DllExport int n;
For specific information about the syntax for extended storage-class modifiers, see Extended Storage-Class Attributes.
