| 7 | This file must be included only to one C++ file in project before | ||
| 8 | declarations of COM interfaces with DEFINE_GUID macro. | ||
| 9 | |||
| 10 | Each GUID must be initialized exactly once in project. | ||
| 11 | There are two different versions of the DEFINE_GUID macro in guiddef.h (MyGuidDef.h): | ||
| 12 | - if INITGUID is not defined: DEFINE_GUID declares an external reference to the symbol name. | ||
| 13 | - if INITGUID is defined: DEFINE_GUID initializes the symbol name to the value of the GUID. | ||
| 14 | |||
| 15 | Also we need IID_IUnknown that is initialized in some file for linking: | ||
| 16 | MSVC: by default the linker uses some lib file that contains IID_IUnknown | ||
| 17 | MinGW: add -luuid switch for linker | ||
| 18 | WinCE: we define IID_IUnknown in this file | ||
| 19 | Other: we define IID_IUnknown in this file | ||
