This directive makes types that have already been compiled into another type library available to the library currently being created. All importlib directives must precede the other type descriptions in the library.
importlib(filename);
The importlib directive makes any type defined in the imported library accessible from within the library being compiled. Ambiguity is resolved as the current library is searched for the type. If the type cannot be found, MkTypLib searches the imported library that is lexically first, and then the next, and so on. To import a type name in code, the name should be entered as libname.typename, where libname is the library name as it appeared in the library statement when the library was compiled.
The imported type library should be distributed with the library being compiled.
The following example imports the libraries Stdole.tlb and Mydisp.tlb:
library BrowseHelper
{
importlib("stdole.tlb");
importlib("mydisp.tlb");
// Additional text omitted.
}
