/*

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