c++ Attributes
			==============


Replacing IDL
-------------
[coclass]
class...

Adds base classes (replaces the IDL coclass statement).


Class Factory
-------------
[coclass, noncreatable]

When not using class factory, you need to override the registration of the class by using the "noncreate" statement.


Interfaces
----------
[dual] or [dispinterface] or [object]
"__interface" keyword enforce the rules of COM interfaces.


COM_INTERFACE_ENTRY
-------------------
[coclass, com_interface_entry("COM_INTERFACE_ENTRY(IMyInterface)")]
class...

Use this to add your own entries to the interface map.


RGS
---
[coclass, registration_script(script="my.rgs")]


Component Categories
--------------------
[coclass, implements_category("CATID_Insertable")]


Code Modules
------------
[module(dll, name="OneFileServer")];

Attributes can be used to generate code module entry points:
[module(dll, name="Test"), idl_module(name="TestModule", dllname="test.dll")];
[idl_module(name="TestModule"), entry("MyFunc")]

If you change "dll" to "exe" and omit the /LD switch, the code will generate an EXE COM server.


Threading Model
---------------
[coclass, threading("free")]

threading parameters	- apartment, single, free, neutral, both, rental

A component that does not provide synchronization should run in an STA, and a component that protects its thread-sensitive code can run in the MTA.

If a component requires a window message queue (for example it has a user interface) or it has thread affinity (it uses
thread local storage), then it must run in an STA.

MTA	- multithreaded apartment
STA	- singlethreaded apartment
