Changes in ASIO 2.3 since ASIO 2.2
- added host queries to detect the driver's buffering and drop-out detection capabilities
- some additional documentation on MMCSS; see page 46 of 'ASIO SDK 2.3.pdf'
- dropped support for Mac OS 8 and 9
Changes in ASIO 2.2 since ASIO 2.1
- added support for Windows 64 bit
Changes in ASIO 2.1 since ASIO 2.0
- Sony DSD support added
- fixed Windows registry sample to HKEY_LOCAL_MACHINE
- fixed a definition problem for input monitoring

// Base class hierachy for creating COM objects, December 1994
/*
a. Derive your COM object from CUnknown
b. Make a static CreateInstance function that takes an LPUNKNOWN, an HRESULT *
and a TCHAR *. The LPUNKNOWN defines the object to delegate IUnknown calls
to. The HRESULT * allows error codes to be passed around constructors and
the TCHAR * is a descriptive name that can be printed on the debugger.
It is important that constructors only change the HRESULT * if they have
to set an ERROR code, if it was successful then leave it alone or you may
overwrite an error code from an object previously created.
When you call a constructor the descriptive name should be in static store
as we do not copy the string. To stop large amounts of memory being used
in retail builds by all these static strings use the NAME macro,
CMyFilter = new CImplFilter(NAME("My filter"),pUnknown,phr);
if (FAILED(hr)) {
return hr;
}
In retail builds NAME(_x_) compiles to NULL, the base CBaseObject class
knows not to do anything with objects that don't have a name.
c. Have a constructor for your object that passes the LPUNKNOWN, HRESULT * and
TCHAR * to the CUnknown constructor. You can set the HRESULT if you have an
error, or just simply pass it through to the constructor.
The object creation will fail in the class factory if the HRESULT indicates
an error (ie FAILED(HRESULT) == TRUE)
d. Create a FactoryTemplate with your object's class id and CreateInstance
function.
Then (for each interface) either
Multiple inheritance
1. Also derive it from ISomeInterface
2. Include DECLARE_IUNKNOWN in your class definition to declare
implementations of QueryInterface, AddRef and Release that
call the outer unknown
3. Override NonDelegatingQueryInterface to expose ISomeInterface by
code something like
if (riid == IID_ISomeInterface) {
return GetInterface((ISomeInterface *) this, ppv);
} else {
return CUnknown::NonDelegatingQueryInterface(riid, ppv);
}
4. Declare and implement the member functions of ISomeInterface.
or: Nested interfaces
1. Declare a class derived from CUnknown
2. Include DECLARE_IUNKNOWN in your class definition
3. Override NonDelegatingQueryInterface to expose ISomeInterface by
code something like
if (riid == IID_ISomeInterface) {
return GetInterface((ISomeInterface *) this, ppv);
} else {
return CUnknown::NonDelegatingQueryInterface(riid, ppv);
}
4. Implement the member functions of ISomeInterface. Use GetOwner() to
access the COM object class.
And in your COM object class:
5. Make the nested class a friend of the COM object class, and declare
an instance of the nested class as a member of the COM object class.
NOTE that because you must always pass the outer unknown and an hResult
to the CUnknown constructor you cannot use a default constructor, in
other words you will have to make the member variable a pointer to the
class and make a NEW call in your constructor to actually create it.
6. override the NonDelegatingQueryInterface with code like this:
if (riid == IID_ISomeInterface) {
return m_pImplFilter->
NonDelegatingQueryInterface(IID_ISomeInterface, ppv);
} else {
return CUnknown::NonDelegatingQueryInterface(riid, ppv);
}
You can have mixed classes which support some interfaces via multiple
inheritance and some via nested classes

#ifndef __WXDEBUG__
#define __WXDEBUG__
// Avoid conflict with MFC
#undef ASSERT
// This library provides fairly straight forward debugging functionality, this
// is split into two main sections. The first is assertion handling, there are
// three types of assertions provided here. The most commonly used one is the
// ASSERT(condition) macro which will pop up a message box including the file
// and line number if the condition evaluates to FALSE. Then there is the
// EXECUTE_ASSERT macro which is the same as ASSERT except the condition will
// still be executed in NON debug builds. The final type of assertion is the
// KASSERT macro which is more suitable for pure (perhaps kernel) filters as
// the condition is printed onto the debugger rather than in a message box.
//
// The other part of the debug module facilties is general purpose logging.
// This is accessed by calling DbgLog(). The function takes a type and level
// field which define the type of informational string you are presenting and
// it's relative importance. The type field can be a combination (one or more)
// of LOG_TIMING, LOG_TRACE, LOG_MEMORY, LOG_LOCKING and LOG_ERROR. The level
// is a DWORD value where zero defines highest important. Use of zero as the
// debug logging level is to be encouraged ONLY for major errors or events as
// they will ALWAYS be displayed on the debugger. Other debug output has it's
// level matched against the current debug output level stored in the registry
// for this module and if less than the current setting it will be displayed.
//
// Each module or executable has it's own debug output level for each of the
// five types. These are read in when the DbgInitialise function is called
// for DLLs linking to STRMBASE.LIB this is done automatically when the DLL
// is loaded, executables must call it explicitely with the module instance
// handle given to them through the WINMAIN entry point. An executable must
// also call DbgTerminate when they have finished to clean up the resources
// the debug library uses, once again this is done automatically for DLLs
// These are the five different categories of logging information
enum { LOG_TIMING = 0x01, // Timing and performance measurements
LOG_TRACE = 0x02, // General step point call tracing

Asiosample
This sample driver illustrates the implementation of an ASIO driver.
Windows notes:
For Windows a COM implementation is provided. The final driver can be
installed in the system by dragging the asiosample.dll onto the
regsvr32.exe in the windows\system directory.
It is normal that the LNK4104 warning is issued for the following 4
exported symbols:
DllGetClassObject
DllCanUnloadNow
DllRegisterServer
DllUnregisterServer
Macintosh notes:
The supplied project is created with CodeWarrior Pro 5.

Steinberg Audio Stream I/O API

charlie (May 1996)
asiosmpl.cpp
sample implementation of asio. can be set to simulate input with some
stupid oscillators.
this driver doesn't output sound at all...
timing is done via the extended time manager on the mac, and
a simple thread on pc.
you may test various configurations by changing the kNumInputs/Outputs,
and kBlockFrames. note that when using wave generation, as i/o is not optimized
at all, it moves quite a bit of memory, too many i/o channels may make it
pretty slow.
if you use this file as a template, make sure to resolve places where the
search string !!! can be found...
