/*++ Copyright (c) 1991 Microsoft Corporation Module Name: imports.idl Abstract: This file is useful for creating RPC interfaces that require the use of types defined in other header files. The .idl file for the RPC product should contain a line in the interface body that imports this file. For example: import "imports.idl"; Doing this causes the MIDL generated header file to contain the include lines that are in this file. If this technique is not used, and instead the .idl file for the RPC product simply contains #include , then the contents of windef.h will be expanded in the MIDL generated header file. This can lead to duplicate definition problems later when the RPC client or RPC server code needs to include both the MIDL generated header file and a file that is included in windef.h.
