/** \page cometcalllogging Call Logging
This is a feature of the comet interfaces that allows the server to log all
calls to any of the interface methods. It logs parameter values, and also allows
logging of errors (see \ref comethandleexception ).
Call logging in comet is enabled by using <kbd>tlb2h -L</kbd> (see \ref tlb2husage).
To enable logging to a specified file, define COMET_LOGFILE and define
COMET_LOGFILE_DEFAULT to be the required logfile (see comet::stream_call_logger_t).
To override logging, specialise comet::call_logger_<true> and implement all the interfaces
defined by the default comet::call_logger_.
How various parameter types are output can be modified by specialising the
function comet::comet_log.

* \page cometrawcomaccess Raw COM Acces
* The designers of Comet have tried to avoid making the wrappers do too much
* implicitly, prefering discrete but explicit ways of triggering functionality.
*
* In order to provide interaction of Comet classes with their COM counterparts,
* a standard set of methods have been used, effectively providing a COM wrapper
* <i>concept</i>.
*
* <ul>
* <li><b>in()</b>: Return a pointer suitable for [in] parameters,</li>
* <li><b>out()</b>: Return a pointer suitable for [out] parameters, first freeing memory allocated,</li>
* <li><b>inout()</b>: Return a pointer suitable for [in,out] parameters.</li>
* <li><b>detach()</b>: Detach and return the internal pointer from the object</li>
* <li><b>in_ptr()</b>: {optional} Return a pointer suitable for [out] parameter where a pointer is required, first freeing memory allocated</li>
* <li><b>get()</b>: {optional} Returns a pointer to the internal pointer (same as STL pointers)</li>
* <li><b>auto_attach( RAW_TYPE )</b>: Cause an assignment to attach the object to the specified raw COM type.</li>
* <li><b>create_reference( RAW_TYPE )</b>: Static method to create a propper wrapper reference to the specified raw object.</li>
* <li><b>create_const_reference( RAW_TYPE )</b>: Static method to create a const wrapper reference to the specified raw object.</li>
* </ul>

/** \page cometcatchallexception Exception Catching Policy
In an ideal world, Microsoft would have adhered to the C++ standard, and made
<kbd>catch(...)</kbd> not catch system exceptions like 'Access Violation',
however this is not the case.
To make it worse, not only do system exceptions get caught by <kbd>catch(...)</kbd>,
they also <b>bypass the stack unwinding</b>. This is quite problematic in an
environment where this mechanism is relied upon for resource management, commonly
'only' memory, but also including multithreading acces control mechanisms.
One of the big problems with Access Violations is that it is an unplanned
exception, and in many situations will leave data structures incomplete,
resources locked or other equally vicious artifacts. Essentially, it breaks
invariants. One viable take on this is that if you don't know where an
exception came from, you shouldn't be catching it.
A big advantage of letting access violations and it's ilk (or any other
unplanned exception) through is that these will then get caught by the JIT (Just
In Time) handlers such as Dr. Watson and Compiler environments that allow
immediate or post-mortem debugging of the problem. A lot of projects (like
Mozilla) have their own bug-reporting which can intercept the bugs at the top
level and generate their own crash dumps, and catching these exceptions is
actually going to bypass a very useful mechanism.
All this is to say that we have made a shift away from exception handling
policies that cause system expeptions to be caught, however in order to
allow as much flexibility as possible, an improved exception handling mechanism
has been added to the interface implementations and to the server implementation
that uses catch and rethrow to allow logging and custom handling of all exceptions.
The default action of the mechanisms will be to finally rethrow unknown
exceptions. The good thing about this is that the rethrow behaves to a JIT handler
as if the expeption had never been caught.

/** \page cometautoexp Comet AutoExp.Dat Support
There is a largely undocumented feature is Visual Studio 6 and 7 that allows
you to create a dll 'ADDIN' that provides custom formatting for variables in the
debugger. CometAutoExp.dll allows you to view simple automation types in more
detail than currently provided internally by the debugger.
By enabling this, you will get to see real date/times when you view datetime_t, you
get to see SAFEARRAY types (including IIDs), and possibly their contents, you
will see full VARIANT types, including SAFEARRAYs.
The file in comet/src/cometautoexp/AutoExp.dat shows the entries that will
be needed to included in your own AutoExp.dat for this to work. (Usually
found at "c:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\AUTOEXP.DAT")
See \ref cometautoexpusage for more information on how to use this.

/** \page cometdefineconfiguration Comet Configuation
While Comet barely uses macros for the import work of creating a COM library,
there are a number of preprocessor switches that are used to alter certain
behaviours and select code. While most of these refer to the compiler being used,
there are a few that are intended to be used as external switches.
<ul><li><b>COMET_ALLOW_DECLSPEC_PROPERTY</b> : Wrapper headers include declspec
properties, allowing interface properties to be assigned-to and read as
properties.</li> <li><b>COMET_ASSERT_THROWS</b> : Comet throws
comet::assert_failed when internal assertions fail in debug builds.</li>
<li><b>COMET_ASSERT_THROWS_ALWAYS</b> : Comet throws comet::assert_failed when
internal assertions fail in both debug and release builds.</li>
<li><b>COMET_LOGFILE</b> : See \ref cometcalllogging.</li>
<li><b>COMET_LOGFILE_DEFAULT</b> : See \ref cometcalllogging. </li>
<li><b>COMET_NO_MBCS</b> : Disable comet multi-byte-character-set conversion handling.</li>
<li><b>COMET_NO_MBCS_WARNING</b> : Turn off the warning indicating that sdt::string is not compatible with MBCS.</li>
<li><b>COMET_USE_RAW_WRAPPERS</b> : Tells com_ptr not to use the comet wrappers but to return raw interface pointers. </li>
</ul>
There are also a number of macros that are either utitlity macros, reflect compiler differences
or Comet version differences that may be convenient to use within your own code.
<ul>
<li><b>COMET_ASSERT(expression)</b> : Run-time assert.</li>
<li><b>COMET_STATIC_ASSERT(static-expression)</b> : Compile-time assert.</li>
<li><b>COMET_NOTUSED(info)</b> : Specify unused argument.</li>
<li><b>COMET_FORCEINLINE </b> : Use before a method to apply force-inline if available. </li>
<li><b>COMET_VARIANT_TRUE,COMET_VARIANT_FALSE</b> : Use in place of VARIANT_TRUE,VARIANT_FALSE to avoid type warnings.</li>
<li><b>COMET_MAJOR_VER </b> : Major comet version</li>
<li><b>COMET_MINOR_VER </b> : Minor comet version</li>
<li><b>COMET_BUILD </b> : Comet version to compare against (yyyymmdd of distribution)</li>
<li><b>COMET_STRICT_TYPENAME </b> : Used for when stricter compilers require 'typename' keyword and VC6 has an error.</li>
<li><b>COMET_CONST_TYPE(vartype, varname, value)</b> : Define a typed constant for a class/struct (or use enum if not supported) </li>
</ul>

Example:
\code
template<> coclass_implementation<Foo> : public coclass<Foo, thread_model::Both, IBar>
\endcode
(Sofus Mortensen)
\li Aggregating another component is now done by adding class aggregates to the type list of interfaces. First template argument of class aggregates is the coclass
to aggregating. The 2, 4, ... template arguments specify which interfaces to aggregate. If no interfaces have been specified, all interfaces will be aggregated.
Example:
\code
template<> coclass_implementation<Foo> : public coclass<Foo, thread_model::Both, aggregates<Bar, IBar> >
\endcode
(Sofus Mortensen)

/** \page cometconnectionpoints Connection Points.
\section cometconnectionpointssource Connction Point Source
Connection points provide events for comet, and rely on tlb2h (see \ref tlb2husage) to generate
the implementation for each method on the interface.
Then comet::implement_cpc is used to provide IConnectionPointContainer
(which provides the method for finding a particular connection point.
The default implementation of a coclass will inherit of this method by
default, however they can be explicitly referenced to provide
alternate implementations.
The class comet::implement_cpc is templated to an interface list, which
can be constructed with comet::make_list.
\code
class my_class : public simple_object< IFooImpl<my_class>, implement_cpc< make_list<IFooEvent, IBarEvent>::result > >
\endcode
This causes each of the interface in the list of interfaces to be wrapped by a
comet::connection_point_for class which provides the access syntax.
\code
connection_point_for<IFooEvent>::connection_point.Fire_FooMethod( args );
\endcode
Note that \b Fire_ is prepended to each method name.
If there is only one connection point in the list, then the
connection_point_for namespace segregator is not required.
If there is no connection point implementation for the interface, then you should make
sure that it is referenced with a [source] tag by a coclass definition
in the library you are including, and that you are generating server
implementations or forcing it by prepending '*' in a symbol file, see
the \ref wrappergensymbolformat.
\section cometconnectionpointsink Connction Point Sink
In order to prevent the circular references inherent in connection points, the
reference loop must be broken somehow. This is best done by using a contained
member that calls back on the parent class.
The class sink_impl is best used in this circumstance as it contains code for calling
Advise and Unadvise. It inherits from static_object which is designed to be embedded in
a class, and does reference counting on the module and does not destruct itself.
This class is templated to the interface implementation desired, which will
mostly be the 'Impl' class for the interface, but might be a raw COM interface.
In this example we have a class 'MyCoclass' that is sinking the event interface IMyEventImpl which
has a single 'EventHappened' method.
\code
class coclass_MyCoclass : public coclass<MyCoclass>
{
// Private Embedded sink implementation.
struct sink_t : sink_impl<IMyEventImpl>
{
sink_t(coclass_MyCoclass *Parent) :m_parent(Parent) {}
inline void EventHappened( long param_Here ) { m_parent->sink_EventHappened(param_Here); }
coclass_MyCoclass *m_parent; // Non-addref reference.
} m_sink;
public:
coclass_MyCoclass() : m_sink(this) {}
// Set the event source.
void SetEventSource( const com_ptr<IUnknown> &unknown)
{
if (m_sink.is_advised())
m_sink.unadvise();
m_sink.advise( unknown );
}
inline void sink_EventHappened( long param_Here )
{
// Event code goes here
}
};

This allows the user to define how exception handling happens for a particular library.
Unfortunately due to a compiler bug in MSVC 6 (fixed in 7), some of the

the customisability originally designed for).
To override the default behavior, specialise the struct

Don't try putting a try catch round a throw in \p catcher_all as the resulting destruct-twice
of the exception when using MSV6 will cause very hard to trace bugs.

/** \page cometlwlock Lightweight Lock
This lightweight lock class was adapted from samples and ideas that
were put across the ATL mailing list. It is a non-starving, kernel-
free lock that does not order writer requests. It is optimized for
use with resources that can take multiple simultaneous reads,
particularly when writing is only an occasional task.
Multiple readers may acquire the lock without any interference with
one another. As soon as a writer requests the lock, additional
readers will spin. When the pre-writer readers have all given up
control of the lock, the writer will obtain it. After the writer
has rescinded control, the additional readers will gain access
to the locked resource.
This class is very lightweight. It does not use any kernel objects.
It is designed for rapid access to resources without requiring
code to undergo process and ring changes. Because the "spin"
method for this lock is "Sleep(0)", it is a good idea to keep
the lock only long enough for short operations; otherwise, CPU
will be wasted spinning for the lock. You can change the spin
mechanism by #define'ing COMET_LW_LOCK_SPIN before including this
header file.
VERY VERY IMPORTANT: If you have a lock open with read access and
attempt to get write access as well, you will deadlock! Always
rescind your read access before requesting write access (and,
of course, don't rely on any read information across this).
This lock works in a single process only. It cannot be used, as is,
for cross-process synchronization. To do that, you should convert
this lock to using a semaphore and mutex, or use shared memory to
avoid kernel objects.

/** \page comettstring Comet tstring type.

* \link comet::tstring tstring \endlink are all or most of the other STL
* classes that have a \p char argument to the templates.
*
* In addition to being used by comet, this is a generally useful series
* of typedefs to be used when combining STL types with tchar.h compatible
* projects.
*
* There are two area to be particularly wary of with STL and tchar.h.
*
* The first is that the filename argument for file streams are always
* narrow char *. I would suggest using a #comet::bstr_t which will
* convert for you, especially in UNICODE (actually UCS2 little-endien) projects.
*
* The second is that tstring support for multi-byte character strings is
* very minimal. Embedded NULLs in the stream are not a problem for
* copying around, however none of the parsing/searching/comparison
* methods cope with multi-byte character sets.
*
* I believe that part of the reason for this is the platform specific
* nature of multi-byte, and the internal support for a variety of
* different MBCS implementations by Microsoft.
