Exporting DLL Functions and Variables
When a program uses a DLL, it can access only the functions or variables that the DLL exports. The DLL can export only globally declared functions and variables. The DLL cannot export functions and variables you declare as static.
If you create your DLL in LabWindows/CVI, you can indicate which functions and variables to export in three ways: using the include file method, using the export qualifier method, and using both the include file and export qualifier methods.
