-This document contains information to help you compile PortAudio with
-ASIO support. If you find any omissions or errors in this document
-please notify Ross Bencina <rossb@audiomulch.com>.
-
-
-Building PortAudio with ASIO support
-------------------------------------
-
-To build PortAudio with ASIO support you need to compile and link with
-pa_asio.c, and files from the ASIO SDK (see below), along with the common
-files from pa_common/ and platform specific files from pa_win/ (for Win32)
-or pa_mac/ (for Macintosh).
-
-If you are compiling with a non-Microsoft compiler on windows, also
-compile and link with iasiothiscallresolver.cpp (see below for
-an explanation).
-
-For some platforms (MingW, possibly Mac), you may simply
-be able to type:
-
-./configure --with-host_os=mingw --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
-make
-
-./configure --with-host_os=darwin --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
-make
-
-and life will be good.
-
-
-Obtaining the ASIO SDK
-----------------------
-
-In order to build PortAudio with ASIO support, you need to download
-the ASIO SDK (version 2.0) from Steinberg. Steinberg makes the ASIO
-SDK available to anyone free of charge, however they do not permit its
-source code to be distributed.
-
-NOTE: In some cases the ASIO SDK may require patching, see below
-for further details.
-
-http://www.steinberg.net/en/ps/support/3rdparty/asio_sdk/
-
-If the above link is broken search Google for:
-"download steinberg ASIO SDK"
-
-
-
-Building the ASIO SDK on Macintosh
-----------------------------------
-
-To build the ASIO SDK on Macintosh you need to compile and link with the
-following files from the ASIO SDK:
-
-host/asiodrivers.cpp
-host/mac/asioshlib.cpp
-host/mac/codefragements.cpp
-
-
-
-Building the ASIO SDK on Windows
---------------------------------
-
-To build the ASIO SDK on Windows you need to compile and link with the
-following files from the ASIO SDK:
-
-asio_sdk\common\asio.cpp
-asio_sdk\host\asiodrivers.cpp
-asio_sdk\host\pc\asiolist.cpp
-
-You may also need to adjust your include paths to support inclusion of
-header files from the above directories.
-
-The ASIO SDK depends on the following COM API functions:
-CoInitialize, CoUninitialize, CoCreateInstance, CLSIDFromString
-For compilation with MinGW you will need to link with -lole32, for
-Borland link with Import32.lib.
-
-
-
-Non-Microsoft (MSVC) Compilers on Windows including Borland and GCC
--------------------------------------------------------------------
-
-Steinberg did not specify a calling convention in the IASIO interface
-definition. This causes the Microsoft compiler to use the proprietary
-thiscall convention which is not compatible with other compilers, such
-as compilers from Borland (BCC and C++Builder) and GNU (gcc).
-Steinberg's ASIO SDK will compile but crash on initialization if
-compiled with a non-Microsoft compiler on Windows.
-
-PortAudio solves this problem using the iasiothiscallresolver library
-which is included in the distribution. When building ASIO support for
-non-Microsoft compilers, be sure to compile and link with
-iasiothiscallresolver.cpp. Note that iasiothiscallresolver includes
-conditional directives which cause it to have no effect if it is
-compiled with a Microsoft compiler, or on the Macintosh.
-
-If you use configure and make (see above), this should be handled
-automatically for you.
-
-For further information about the IASIO thiscall problem see this page:
-http://www.audiomulch.com/~rossb/code/calliasio
-
-
-
-Macintosh ASIO SDK Bug Patch
-----------------------------
-
-There is a bug in the ASIO SDK that causes the Macintosh version to
-often fail during initialization. Below is a patch that you can apply.
-
-In codefragments.cpp replace getFrontProcessDirectory function with
-the following one (GetFrontProcess replaced by GetCurrentProcess).
-
-
-bool CodeFragments::getFrontProcessDirectory(void *specs)
-{
- FSSpec *fss = (FSSpec *)specs;
- ProcessInfoRec pif;
- ProcessSerialNumber psn;
-
- memset(&psn,0,(long)sizeof(ProcessSerialNumber));
- // if(GetFrontProcess(&psn) == noErr) // wrong !!!
- if(GetCurrentProcess(&psn) == noErr) // correct !!!
- {
- pif.processName = 0;
- pif.processAppSpec = fss;
- pif.processInfoLength = sizeof(ProcessInfoRec);
- if(GetProcessInformation(&psn, &pif) == noErr)
- return true;
- }
- return false;

- IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for
- the top level description - this comment describes the technical details of
- the implementation.
-

- http://www.audiomulch.com/~rossb/code/calliasio
-

-
- BACKGROUND
-
- The IASIO interface declared in the Steinberg ASIO 2 SDK declares
- functions with no explicit calling convention. This causes MSVC++ to default
- to using the thiscall convention, which is a proprietary convention not
- implemented by some non-microsoft compilers - notably borland BCC,
- C++Builder, and gcc. MSVC++ is the defacto standard compiler used by
- Steinberg. As a result of this situation, the ASIO sdk will compile with
- any compiler, however attempting to execute the compiled code will cause a
- crash due to different default calling conventions on non-Microsoft
- compilers.
-
- IASIOThiscallResolver solves the problem by providing an adapter class that
- delegates to the IASIO interface using the correct calling convention
- (thiscall). Due to the lack of support for thiscall in the Borland and GCC
- compilers, the calls have been implemented in assembly language.
-
- A number of macros are defined for thiscall function calls with different
- numbers of parameters, with and without return values - it may be possible
- to modify the format of these macros to make them work with other inline
- assemblers.
-
-
- THISCALL DEFINITION
-
- A number of definitions of the thiscall calling convention are floating
- around the internet. The following definition has been validated against
- output from the MSVC++ compiler:
-
- For non-vararg functions, thiscall works as follows: the object (this)
- pointer is passed in ECX. All arguments are passed on the stack in
- right to left order. The return value is placed in EAX. The callee
- clears the passed arguments from the stack.
-
-
- FINDING FUNCTION POINTERS FROM AN IASIO POINTER
-
- The first field of a COM object is a pointer to its vtble. Thus a pointer
- to an object implementing the IASIO interface also points to a pointer to
- that object's vtbl. The vtble is a table of function pointers for all of
- the virtual functions exposed by the implemented interfaces.
-
- If we consider a variable declared as a pointer to IASO:
-
- IASIO *theAsioDriver
-
- theAsioDriver points to:
-
- object implementing IASIO
- {
- IASIOvtbl *vtbl
- other data
- }
-
- in other words, theAsioDriver points to a pointer to an IASIOvtbl
-
- vtbl points to a table of function pointers:
-
- IASIOvtbl ( interface IASIO : public IUnknown )
- {
- (IUnknown functions)
- 0 virtual HRESULT STDMETHODCALLTYPE (*QueryInterface)(REFIID riid, void **ppv) = 0;
- 4 virtual ULONG STDMETHODCALLTYPE (*AddRef)() = 0;
- 8 virtual ULONG STDMETHODCALLTYPE (*Release)() = 0;
-
- (IASIO functions)
- 12 virtual ASIOBool (*init)(void *sysHandle) = 0;
- 16 virtual void (*getDriverName)(char *name) = 0;
- 20 virtual long (*getDriverVersion)() = 0;
- 24 virtual void (*getErrorMessage)(char *string) = 0;
- 28 virtual ASIOError (*start)() = 0;
- 32 virtual ASIOError (*stop)() = 0;
- 36 virtual ASIOError (*getChannels)(long *numInputChannels, long *numOutputChannels) = 0;
- 40 virtual ASIOError (*getLatencies)(long *inputLatency, long *outputLatency) = 0;
- 44 virtual ASIOError (*getBufferSize)(long *minSize, long *maxSize,
- long *preferredSize, long *granularity) = 0;
- 48 virtual ASIOError (*canSampleRate)(ASIOSampleRate sampleRate) = 0;
- 52 virtual ASIOError (*getSampleRate)(ASIOSampleRate *sampleRate) = 0;
- 56 virtual ASIOError (*setSampleRate)(ASIOSampleRate sampleRate) = 0;
- 60 virtual ASIOError (*getClockSources)(ASIOClockSource *clocks, long *numSources) = 0;
- 64 virtual ASIOError (*setClockSource)(long reference) = 0;
- 68 virtual ASIOError (*getSamplePosition)(ASIOSamples *sPos, ASIOTimeStamp *tStamp) = 0;
- 72 virtual ASIOError (*getChannelInfo)(ASIOChannelInfo *info) = 0;
- 76 virtual ASIOError (*createBuffers)(ASIOBufferInfo *bufferInfos, long numChannels,
- long bufferSize, ASIOCallbacks *callbacks) = 0;
- 80 virtual ASIOError (*disposeBuffers)() = 0;
- 84 virtual ASIOError (*controlPanel)() = 0;
- 88 virtual ASIOError (*future)(long selector,void *opt) = 0;
- 92 virtual ASIOError (*outputReady)() = 0;
- };
-
- The numbers in the left column show the byte offset of each function ptr
- from the beginning of the vtbl. These numbers are used in the code below
- to select different functions.
-
- In order to find the address of a particular function, theAsioDriver
- must first be dereferenced to find the value of the vtbl pointer:
-
- mov eax, theAsioDriver
- mov edx, [theAsioDriver] // edx now points to vtbl[0]
-
- Then an offset must be added to the vtbl pointer to select a
- particular function, for example vtbl+44 points to the slot containing
- a pointer to the getBufferSize function.
-
- Finally vtbl+x must be dereferenced to obtain the value of the function
- pointer stored in that address:
-
- call [edx+44] // call the function pointed to by
- // the value in the getBufferSize field of the vtbl
-
-
- SEE ALSO
-
- Martin Fay's OpenASIO DLL at http://www.martinfay.com solves the same
- problem by providing a new COM interface which wraps IASIO with an
- interface that uses portable calling conventions. OpenASIO must be compiled
- with MSVC, and requires that you ship the OpenASIO DLL with your
- application.

-
- ACKNOWLEDGEMENTS
-
- Ross Bencina: worked out the thiscall details above, wrote the original
- Borland asm macros, and a patch for asio.cpp (which is no longer needed).
- Thanks to Martin Fay for introducing me to the issues discussed here,
- and to Rene G. Ceballos for assisting with asm dumps from MSVC++.
-
- Antti Silvast: converted the original calliasio to work with gcc and NASM
- by implementing the asm code in a separate file.
-
- Fraser Adams: modified the original calliasio containing the Borland inline
- asm to add inline asm for gcc i.e. Intel syntax for Borland and AT&T syntax
- for gcc. This seems a neater approach for gcc than to have a separate .asm
- file and it means that we only need one version of the thiscall patch.
-
- Fraser Adams: rewrote the original calliasio patch in the form of the
- IASIOThiscallResolver class in order to avoid modifications to files from
- the Steinberg SDK, which may have had potential licence issues.
-
- Andrew Baldwin: contributed fixes for compatibility problems with more
- recent versions of the gcc assembler.

-// ****************************************************************************
-// File: IASIOThiscallResolver.h
-// Description: The IASIOThiscallResolver class implements the IASIO
-// interface and acts as a proxy to the real IASIO interface by
-// calling through its vptr table using the thiscall calling
-// convention. To put it another way, we interpose
-// IASIOThiscallResolver between ASIO SDK code and the driver.
-// This is necessary because most non-Microsoft compilers don't
-// implement the thiscall calling convention used by IASIO.
-//
-// iasiothiscallresolver.cpp contains the background of this
-// problem plus a technical description of the vptr
-// manipulations.
-//
-// In order to use this mechanism one simply has to add
-// iasiothiscallresolver.cpp to the list of files to compile
-// and #include <iasiothiscallresolver.h>
-//
-// Note that this #include must come after the other ASIO SDK
-// #includes, for example:
-//
-// #include <windows.h>
-// #include <asiosys.h>
-// #include <asio.h>
-// #include <asiodrivers.h>
-// #include <iasiothiscallresolver.h>
-//
-// Actually the important thing is to #include
-// <iasiothiscallresolver.h> after <asio.h>. We have
-// incorporated a test to enforce this ordering.
-//
-// The code transparently takes care of the interposition by
-// using macro substitution to intercept calls to ASIOInit()
-// and ASIOExit(). We save the original ASIO global
-// "theAsioDriver" in our "that" variable, and then set
-// "theAsioDriver" to equal our IASIOThiscallResolver instance.
-//
-// Whilst this method of resolving the thiscall problem requires
-// the addition of #include <iasiothiscallresolver.h> to client
-// code it has the advantage that it does not break the terms
-// of the ASIO licence by publishing it. We are NOT modifying
-// any Steinberg code here, we are merely implementing the IASIO
-// interface in the same way that we would need to do if we
-// wished to provide an open source ASIO driver.
-//
-// For compilation with MinGW -lole32 needs to be added to the
-// linker options. For BORLAND, linking with Import32.lib is
-// sufficient.
-//
-// The dependencies are with: CoInitialize, CoUninitialize,
-// CoCreateInstance, CLSIDFromString - used by asiolist.cpp
-// and are required on Windows whether ThiscallResolver is used
-// or not.
-//
-// Searching for the above strings in the root library path
-// of your compiler should enable the correct libraries to be
-// identified if they aren't immediately obvious.
-//
-// Note that the current implementation of IASIOThiscallResolver
-// is not COM compliant - it does not correctly implement the
-// IUnknown interface. Implementing it is not necessary because
-// it is not called by parts of the ASIO SDK which call through
-// theAsioDriver ptr. The IUnknown methods are implemented as
-// assert(false) to ensure that the code fails if they are
-// ever called.
-// Restrictions: None. Public Domain & Open Source distribute freely
-// You may use IASIOThiscallResolver commercially as well as
-// privately.
-// You the user assume the responsibility for the use of the
-// files, binary or text, and there is no guarantee or warranty,
-// expressed or implied, including but not limited to the
-// implied warranties of merchantability and fitness for a
-// particular purpose. You assume all responsibility and agree
-// to hold no entity, copyright holder or distributors liable
-// for any loss of data or inaccurate representations of data
-// as a result of using IASIOThiscallResolver.
-// Version: 1.4 Added separate macro CALL_THISCALL_1_DOUBLE from
-// Andrew Baldwin, and volatile for whole gcc asm blocks,
-// both for compatibility with newer gcc versions. Cleaned up
-// Borland asm to use one less register.
-// 1.3 Switched to including assert.h for better compatibility.
-// Wrapped entire .h and .cpp contents with a check for
-// _MSC_VER to provide better compatibility with MS compilers.
-// Changed Singleton implementation to use static instance
-// instead of freestore allocated instance. Removed ASIOExit
-// macro as it is no longer needed.
-// 1.2 Removed semicolons from ASIOInit and ASIOExit macros to
-// allow them to be embedded in expressions (if statements).
-// Cleaned up some comments. Removed combase.c dependency (it
-// doesn't compile with BCB anyway) by stubbing IUnknown.
-// 1.1 Incorporated comments from Ross Bencina including things
-// such as changing name from ThiscallResolver to
-// IASIOThiscallResolver, tidying up the constructor, fixing
-// a bug in IASIOThiscallResolver::ASIOExit() and improving
-// portability through the use of conditional compilation
-// 1.0 Initial working version.

-*/
-
-/** @file
-
- Note that specific support for paInputUnderflow, paOutputOverflow and
- paNeverDropInput is not necessary or possible with this driver due to the
- synchronous full duplex double-buffered architecture of ASIO.
-
- @todo check that CoInitialize()/CoUninitialize() are always correctly
- paired, even in error cases.
-
- @todo implement host api specific extension to set i/o buffer sizes in frames
-
- @todo implement ReadStream, WriteStream, GetStreamReadAvailable, GetStreamWriteAvailable
-
- @todo implement IsFormatSupported
-
- @todo work out how to implement stream stoppage from callback and
- implement IsStreamActive properly. Stream stoppage could be implemented
- using a high-priority thread blocked on an Event which is signalled
- by the callback. Or, we could just call ASIO stop from the callback
- and see what happens.
-
- @todo rigorously check asio return codes and convert to pa error codes
-
- @todo Different channels of a multichannel stream can have different sample
- formats, but we assume that all are the same as the first channel for now.
- Fixing this will require the block processor to maintain per-channel
- conversion functions - could get nasty.
-
- @todo investigate whether the asio processNow flag needs to be honoured
-
- @todo handle asioMessages() callbacks in a useful way, or at least document
- what cases we don't handle.
-
- @todo miscellaneous other FIXMEs
-
- @todo provide an asio-specific method for setting the systems specific
- value (aka main window handle) - check that this matches the value
- passed to PaAsio_ShowControlPanel, or remove it entirely from
- PaAsio_ShowControlPanel. - this would allow PaAsio_ShowControlPanel
- to be called for the currently open stream (at present all streams
- must be closed).
