Specifies one or more header files to be included in the generated .idl file.
[ include( header_file ) ];
The name of a file that you want included in the generated .idl file.
The include C++ attribute causes an
#include statement to be placed below the
import "docobj.idl" statement in the generated .idl file.
The include C++ attribute has the same functionality as the include MIDL attribute.
The following code shows an example of how to use include. For this example, the file include.h contains only a #include statement.
// cpp_attr_ref_include.cpp // compile with: /LD [module(name="MyLib")]; [include(cpp_attr_ref_include.h)];
