/DLL
The /DLL option builds a DLL as the main output file. A DLL usually contains exports that can be used by another program. There are three methods for specifying exports, listed in recommended order of use:
-
__declspec(dllexport) in the source code
-
An EXPORTS statement in a .def file
-
An /EXPORT specification in a LINK command
A program can use more than one method.
Another way to build a DLL is with the LIBRARY module-definition statement. The /BASE and /DLL options together are equivalent to the LIBRARY statement.
Do not specify this option within the development environment; this option is for use only on the command line. This option is set when you create a DLL project with an Application Wizard.
Note that if you create your import library in a preliminary step, before creating your .dll, you must pass the same set of object files when building the .dll, as you passed when building the import library.
