-// DSD operation and buffer layout\r
-// Definition by Steinberg/Sony Oxford.\r
-//\r
-// We have tried to treat DSD as PCM and so keep a consistant structure across\r
-// the ASIO interface.\r
-//\r
-// DSD's sample rate is normally referenced as a multiple of 44.1Khz, so\r
-// the standard sample rate is refered to as 64Fs (or 2.8224Mhz). We looked\r
-// at making a special case for DSD and adding a field to the ASIOFuture that\r
-// would allow the user to select the Over Sampleing Rate (OSR) as a seperate\r
-// entity but decided in the end just to treat it as a simple value of\r
-// 2.8224Mhz and use the standard interface to set it.\r
-//\r
-// The second problem was the "word" size, in PCM the word size is always a\r
-// greater than or equal to 8 bits (a byte). This makes life easy as we can\r
-// then pack the samples into the "natural" size for the machine.\r
-// In DSD the "word" size is 1 bit. This is not a major problem and can easily\r
-// be dealt with if we ensure that we always deal with a multiple of 8 samples.\r
-//\r
-// DSD brings with it another twist to the Endianness religion. How are the\r
-// samples packed into the byte. It would be nice to just say the most significant\r
-// bit is always the first sample, however there would then be a performance hit\r
-// on little endian machines. Looking at how some of the processing goes...\r
-// Little endian machines like the first sample to be in the Least Significant Bit,\r
-// this is because when you write it to memory the data is in the correct format\r
-// to be shifted in and out of the words.\r
-// Big endian machine prefer the first sample to be in the Most Significant Bit,\r
-// again for the same reasion.\r
-//\r
-// And just when things were looking really muddy there is a proposed extension to\r
-// DSD that uses 8 bit word sizes. It does not care what endianness you use.\r
-//\r
-// Switching the driver between DSD and PCM mode\r
-// ASIOFuture allows for extending the ASIO API quite transparently.\r

-\r
-using time info:\r
-it is recommended to use the new method with time info even if the asio\r
-device does not support timecode; continuous calls to ASIOGetSamplePosition\r
-and ASIOGetSampleRate are avoided, and there is a more defined relationship\r
-between callback time and the time info.\r
-\r
-see the example below.\r
-to initiate time info mode, after you have received the callbacks pointer in\r
-ASIOCreateBuffers, you will call the asioMessage callback with kAsioSupportsTimeInfo\r
-as the argument. if this returns 1, host has accepted time info mode.\r
-now host expects the new callback bufferSwitchTimeInfo to be used instead\r
-of the old bufferSwitch method. the ASIOTime structure is assumed to be valid\r
-and accessible until the callback returns.\r
-\r
-using time code:\r
-if the device supports reading time code, it will call host's asioMessage callback\r
-with kAsioSupportsTimeCode as the selector. it may then fill the according\r
-fields and set the kTcValid flag.\r
-host will call the future method with the kAsioEnableTimeCodeRead selector when\r
-it wants to enable or disable tc reading by the device. you should also support\r
-the kAsioCanTimeInfo and kAsioCanTimeCode selectors in ASIOFuture (see example).\r
-\r
-note:\r
-the AsioTimeInfo/ASIOTimeCode pair is supposed to work in both directions.\r
-as a matter of convention, the relationship between the sample\r
-position counter and the time code at buffer switch time is\r
-(ignoring offset between tc and sample pos when tc is running):\r
-\r
-on input: sample 0 -> input buffer sample 0 -> time code 0\r
-on output: sample 0 -> output buffer sample 0 -> time code 0\r
-\r
-this means that for 'real' calculations, one has to take into account\r
-the according latencies.\r
-\r
-example:\r
-\r

- inputLatency will hold the 'age' of the first sample frame\r

- (this is theoretical, meaning it does not include the overhead\r
- and delay between the actual physical switch, and the time\r
- when bufferSitch() enters).\r
- This will usually be the size of one block in sample frames, plus\r
- device specific latencies.\r
-\r
- outputLatency will specify the time between the buffer switch,\r
- and the time when the next play buffer will start to sound.\r
- The next play buffer is defined as the one the host starts\r
- processing after (or at) bufferSwitch(), indicated by the\r
- index parameter (0 for buffer A, 1 for buffer B).\r
- It will usually be either one block, if the host writes directly\r
- to a dma buffer, or two or more blocks if the buffer is 'latched' by\r
- the driver. As an example, on ASIOStart(), the host will have filled\r
- the play buffer at index 1 already; when it gets the callback (with\r
- the parameter index == 0), this tells it to read from the input\r
- buffer 0, and start to fill the play buffer 0 (assuming that now\r
- play buffer 1 is already sounding). In this case, the output\r
- latency is one block. If the driver decides to copy buffer 1\r
- at that time, and pass it to the hardware at the next slot (which\r
- is most commonly done, but should be avoided), the output latency\r
- becomes two blocks instead, resulting in a total i/o latency of at least\r
- 3 blocks. As memory access is the main bottleneck in native dsp processing,\r
- and to acheive less latency, it is highly recommended to try to avoid\r
- copying (this is also why the driver is the owner of the buffers). To\r
- summarize, the minimum i/o latency can be acheived if the input buffer\r
- is processed by the host into the output buffer which will physically\r
- start to sound on the next time slice. Also note that the host expects\r
- the bufferSwitch() callback to be accessed for each time slice in order\r
- to retain sync, possibly recursively; if it fails to process a block in\r
- time, it will suspend its operation for some time in order to recover.\r

-/* Purpose:\r
- this tells the driver that the host has completed processing\r
- the output buffers. if the data format required by the hardware\r
- differs from the supported asio formats, but the hardware\r
- buffers are DMA buffers, the driver will have to convert\r
- the audio stream data; as the bufferSwitch callback is\r
- usually issued at dma block switch time, the driver will\r
- have to convert the *previous* host buffer, which increases\r
- the output latency by one block.\r
- when the host finds out that ASIOOutputReady() returns\r
- true, it will issue this call whenever it completed\r
- output processing. then the driver can convert the\r
- host data directly to the dma buffer to be played next,\r
- reducing output latency by one block.\r
- another way to look at it is, that the buffer switch is called\r
- in order to pass the *input* stream to the host, so that it can\r
- process the input into the output, and the output stream is passed\r
- to the driver when the host has completed its process.\r
- Parameter:\r
- None\r
- Returns:\r
- only if the above mentioned scenario is given, and a reduction\r
- of output latency can be acheived by this mechanism, should\r
- ASE_OK be returned. otherwise (and usually), ASE_NotPresent\r
- should be returned in order to prevent further calls to this\r
- function. note that the host may want to determine if it is\r
- to use this when the system is not yet fully initialized, so\r
- ASE_OK should always be returned if the mechanism makes sense. \r
- Notes:\r
- please remeber to adjust ASIOGetLatencies() according to\r
- whether ASIOOutputReady() was ever called or not, if your\r
- driver supports this scenario.\r
- also note that the engine may fail to call ASIO_OutputReady()\r
- in time in overload cases. as already mentioned, bufferSwitch\r
- should be called for every block regardless of whether a block\r
- could be processed in time.\r

- IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for\r
- the top level description - this comment describes the technical details of\r
- the implementation.\r
-\r
- The latest version of this file is available from:\r
- http://www.audiomulch.com/~rossb/code/calliasio\r
-\r
- please email comments to Ross Bencina <rossb@audiomulch.com>\r
-\r
- BACKGROUND\r
-\r
- The IASIO interface declared in the Steinberg ASIO 2 SDK declares\r
- functions with no explicit calling convention. This causes MSVC++ to default\r
- to using the thiscall convention, which is a proprietary convention not\r
- implemented by some non-microsoft compilers - notably borland BCC,\r
- C++Builder, and gcc. MSVC++ is the defacto standard compiler used by\r
- Steinberg. As a result of this situation, the ASIO sdk will compile with\r
- any compiler, however attempting to execute the compiled code will cause a\r
- crash due to different default calling conventions on non-Microsoft\r
- compilers.\r
-\r
- IASIOThiscallResolver solves the problem by providing an adapter class that\r
- delegates to the IASIO interface using the correct calling convention\r
- (thiscall). Due to the lack of support for thiscall in the Borland and GCC\r
- compilers, the calls have been implemented in assembly language.\r
-\r
- A number of macros are defined for thiscall function calls with different\r
- numbers of parameters, with and without return values - it may be possible\r
- to modify the format of these macros to make them work with other inline\r
- assemblers.\r
-\r
-\r
- THISCALL DEFINITION\r
-\r
- A number of definitions of the thiscall calling convention are floating\r
- around the internet. The following definition has been validated against\r
- output from the MSVC++ compiler:\r
-\r
- For non-vararg functions, thiscall works as follows: the object (this)\r
- pointer is passed in ECX. All arguments are passed on the stack in\r
- right to left order. The return value is placed in EAX. The callee\r
- clears the passed arguments from the stack.\r
-\r
-\r
- FINDING FUNCTION POINTERS FROM AN IASIO POINTER\r
-\r
- The first field of a COM object is a pointer to its vtble. Thus a pointer\r
- to an object implementing the IASIO interface also points to a pointer to\r
- that object's vtbl. The vtble is a table of function pointers for all of\r
- the virtual functions exposed by the implemented interfaces.\r
-\r
- If we consider a variable declared as a pointer to IASO:\r
-\r
- IASIO *theAsioDriver\r
-\r
- theAsioDriver points to:\r
-\r
- object implementing IASIO\r
- {\r
- IASIOvtbl *vtbl\r
- other data\r
- }\r
-\r
- in other words, theAsioDriver points to a pointer to an IASIOvtbl\r
-\r
- vtbl points to a table of function pointers:\r
-\r
- IASIOvtbl ( interface IASIO : public IUnknown )\r
- {\r
- (IUnknown functions)\r
- 0 virtual HRESULT STDMETHODCALLTYPE (*QueryInterface)(REFIID riid, void **ppv) = 0;\r
- 4 virtual ULONG STDMETHODCALLTYPE (*AddRef)() = 0;\r
- 8 virtual ULONG STDMETHODCALLTYPE (*Release)() = 0; \r

- 20 virtual long (*getDriverVersion)() = 0;\r
- 24 virtual void (*getErrorMessage)(char *string) = 0;\r

- };\r
-\r
- The numbers in the left column show the byte offset of each function ptr\r
- from the beginning of the vtbl. These numbers are used in the code below\r
- to select different functions.\r
-\r
- In order to find the address of a particular function, theAsioDriver\r
- must first be dereferenced to find the value of the vtbl pointer:\r
-\r
- mov eax, theAsioDriver\r
- mov edx, [theAsioDriver] // edx now points to vtbl[0]\r
-\r
- Then an offset must be added to the vtbl pointer to select a\r
- particular function, for example vtbl+44 points to the slot containing\r
- a pointer to the getBufferSize function.\r
-\r
- Finally vtbl+x must be dereferenced to obtain the value of the function\r
- pointer stored in that address:\r
-\r
- call [edx+44] // call the function pointed to by\r
- // the value in the getBufferSize field of the vtbl\r
-\r
-\r
- SEE ALSO\r
-\r
- Martin Fay's OpenASIO DLL at http://www.martinfay.com solves the same\r
- problem by providing a new COM interface which wraps IASIO with an\r
- interface that uses portable calling conventions. OpenASIO must be compiled\r
- with MSVC, and requires that you ship the OpenASIO DLL with your\r
- application.\r

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

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

+// DSD operation and buffer layout\r
+// Definition by Steinberg/Sony Oxford.\r
+//\r
+// We have tried to treat DSD as PCM and so keep a consistant structure across\r
+// the ASIO interface.\r
+//\r
+// DSD's sample rate is normally referenced as a multiple of 44.1Khz, so\r
+// the standard sample rate is refered to as 64Fs (or 2.8224Mhz). We looked\r
+// at making a special case for DSD and adding a field to the ASIOFuture that\r
+// would allow the user to select the Over Sampleing Rate (OSR) as a seperate\r
+// entity but decided in the end just to treat it as a simple value of\r
+// 2.8224Mhz and use the standard interface to set it.\r
+//\r
+// The second problem was the "word" size, in PCM the word size is always a\r
+// greater than or equal to 8 bits (a byte). This makes life easy as we can\r
+// then pack the samples into the "natural" size for the machine.\r
+// In DSD the "word" size is 1 bit. This is not a major problem and can easily\r
+// be dealt with if we ensure that we always deal with a multiple of 8 samples.\r
+//\r
+// DSD brings with it another twist to the Endianness religion. How are the\r
+// samples packed into the byte. It would be nice to just say the most significant\r
+// bit is always the first sample, however there would then be a performance hit\r
+// on little endian machines. Looking at how some of the processing goes...\r
+// Little endian machines like the first sample to be in the Least Significant Bit,\r
+// this is because when you write it to memory the data is in the correct format\r
+// to be shifted in and out of the words.\r
+// Big endian machine prefer the first sample to be in the Most Significant Bit,\r
+// again for the same reasion.\r
+//\r
+// And just when things were looking really muddy there is a proposed extension to\r
+// DSD that uses 8 bit word sizes. It does not care what endianness you use.\r
+//\r
+// Switching the driver between DSD and PCM mode\r
+// ASIOFuture allows for extending the ASIO API quite transparently.\r

+\r
+using time info:\r
+it is recommended to use the new method with time info even if the asio\r
+device does not support timecode; continuous calls to ASIOGetSamplePosition\r
+and ASIOGetSampleRate are avoided, and there is a more defined relationship\r
+between callback time and the time info.\r
+\r
+see the example below.\r
+to initiate time info mode, after you have received the callbacks pointer in\r
+ASIOCreateBuffers, you will call the asioMessage callback with kAsioSupportsTimeInfo\r
+as the argument. if this returns 1, host has accepted time info mode.\r
+now host expects the new callback bufferSwitchTimeInfo to be used instead\r
+of the old bufferSwitch method. the ASIOTime structure is assumed to be valid\r
+and accessible until the callback returns.\r
+\r
+using time code:\r
+if the device supports reading time code, it will call host's asioMessage callback\r
+with kAsioSupportsTimeCode as the selector. it may then fill the according\r
+fields and set the kTcValid flag.\r
+host will call the future method with the kAsioEnableTimeCodeRead selector when\r
+it wants to enable or disable tc reading by the device. you should also support\r
+the kAsioCanTimeInfo and kAsioCanTimeCode selectors in ASIOFuture (see example).\r
+\r
+note:\r
+the AsioTimeInfo/ASIOTimeCode pair is supposed to work in both directions.\r
+as a matter of convention, the relationship between the sample\r
+position counter and the time code at buffer switch time is\r
+(ignoring offset between tc and sample pos when tc is running):\r
+\r
+on input: sample 0 -> input buffer sample 0 -> time code 0\r
+on output: sample 0 -> output buffer sample 0 -> time code 0\r
+\r
+this means that for 'real' calculations, one has to take into account\r
+the according latencies.\r

+ to a dma buffer, or two or more blocks if the buffer is 'latched' by\r
+ the driver. As an example, on ASIOStart(), the host will have filled\r
+ the play buffer at index 1 already; when it gets the callback (with\r
+ the parameter index == 0), this tells it to read from the input\r
+ buffer 0, and start to fill the play buffer 0 (assuming that now\r
+ play buffer 1 is already sounding). In this case, the output\r
+ latency is one block. If the driver decides to copy buffer 1\r

+ becomes two blocks instead, resulting in a total i/o latency of at least\r

+ copying (this is also why the driver is the owner of the buffers). To\r
+ summarize, the minimum i/o latency can be acheived if the input buffer\r
+ is processed by the host into the output buffer which will physically\r

+ buffers are DMA buffers, the driver will have to convert\r
+ the audio stream data; as the bufferSwitch callback is\r
+ usually issued at dma block switch time, the driver will\r
+ have to convert the *previous* host buffer, which increases\r
+ the output latency by one block.\r
+ when the host finds out that ASIOOutputReady() returns\r
+ true, it will issue this call whenever it completed\r
+ output processing. then the driver can convert the\r
+ host data directly to the dma buffer to be played next,\r
+ reducing output latency by one block.\r
+ another way to look at it is, that the buffer switch is called\r
+ in order to pass the *input* stream to the host, so that it can\r
+ process the input into the output, and the output stream is passed\r
+ to the driver when the host has completed its process.\r
+ Parameter:\r
+ None\r
+ Returns:\r

+ should be returned in order to prevent further calls to this\r
+ function. note that the host may want to determine if it is\r
+ to use this when the system is not yet fully initialized, so\r
+ ASE_OK should always be returned if the mechanism makes sense. \r
+ Notes:\r
+ please remeber to adjust ASIOGetLatencies() according to\r
+ whether ASIOOutputReady() was ever called or not, if your\r
+ driver supports this scenario.\r
+ also note that the engine may fail to call ASIO_OutputReady()\r
+ in time in overload cases. as already mentioned, bufferSwitch\r
+ should be called for every block regardless of whether a block\r

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

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

+//\r
+// File: IASIOThiscallResolver.h\r
+// Description: The IASIOThiscallResolver class implements the IASIO\r
+// interface and acts as a proxy to the real IASIO interface by\r
+// calling through its vptr table using the thiscall calling\r
+// convention. To put it another way, we interpose\r
+// IASIOThiscallResolver between ASIO SDK code and the driver.\r
+// This is necessary because most non-Microsoft compilers don't\r
+// implement the thiscall calling convention used by IASIO.\r
+//\r
+// iasiothiscallresolver.cpp contains the background of this\r
+// problem plus a technical description of the vptr\r
+// manipulations.\r
+//\r
+// In order to use this mechanism one simply has to add\r
+// iasiothiscallresolver.cpp to the list of files to compile\r
+// and #include <iasiothiscallresolver.h>\r
+//\r
+// Note that this #include must come after the other ASIO SDK\r
+// #includes, for example:\r
+//\r
+// #include <windows.h>\r
+// #include <asiosys.h>\r
+// #include <asio.h>\r
+// #include <asiodrivers.h>\r
+// #include <iasiothiscallresolver.h>\r
+//\r
+// Actually the important thing is to #include\r
+// <iasiothiscallresolver.h> after <asio.h>. We have\r
+// incorporated a test to enforce this ordering.\r
+//\r
+// The code transparently takes care of the interposition by\r
+// using macro substitution to intercept calls to ASIOInit()\r
+// and ASIOExit(). We save the original ASIO global\r
+// "theAsioDriver" in our "that" variable, and then set\r
+// "theAsioDriver" to equal our IASIOThiscallResolver instance.\r
+//\r
+// Whilst this method of resolving the thiscall problem requires\r
+// the addition of #include <iasiothiscallresolver.h> to client\r
+// code it has the advantage that it does not break the terms\r
+// of the ASIO licence by publishing it. We are NOT modifying\r
+// any Steinberg code here, we are merely implementing the IASIO\r
+// interface in the same way that we would need to do if we\r
+// wished to provide an open source ASIO driver.\r
+//\r
+// For compilation with MinGW -lole32 needs to be added to the\r
+// linker options. For BORLAND, linking with Import32.lib is\r
+// sufficient.\r
+//\r
+// The dependencies are with: CoInitialize, CoUninitialize,\r

+// of your compiler should enable the correct libraries to be\r
+// identified if they aren't immediately obvious.\r
+//\r
+// Note that the current implementation of IASIOThiscallResolver\r
+// is not COM compliant - it does not correctly implement the\r
+// IUnknown interface. Implementing it is not necessary because\r
+// it is not called by parts of the ASIO SDK which call through\r
+// theAsioDriver ptr. The IUnknown methods are implemented as\r
+// assert(false) to ensure that the code fails if they are\r
+// ever called.\r
+// Restrictions: None. Public Domain & Open Source distribute freely\r
+// You may use IASIOThiscallResolver commercially as well as\r
+// privately.\r
+// You the user assume the responsibility for the use of the\r

+// Version: 1.4 Added separate macro CALL_THISCALL_1_DOUBLE from\r
+// Andrew Baldwin, and volatile for whole gcc asm blocks,\r
+// both for compatibility with newer gcc versions. Cleaned up\r
+// Borland asm to use one less register.\r
+// 1.3 Switched to including assert.h for better compatibility.\r
+// Wrapped entire .h and .cpp contents with a check for\r
+// _MSC_VER to provide better compatibility with MS compilers.\r
+// Changed Singleton implementation to use static instance\r
+// instead of freestore allocated instance. Removed ASIOExit\r
+// macro as it is no longer needed.\r
+// 1.2 Removed semicolons from ASIOInit and ASIOExit macros to\r
+// allow them to be embedded in expressions (if statements).\r
+// Cleaned up some comments. Removed combase.c dependency (it\r
+// doesn't compile with BCB anyway) by stubbing IUnknown.\r
+// 1.1 Incorporated comments from Ross Bencina including things\r
+// such as changing name from ThiscallResolver to\r
+// IASIOThiscallResolver, tidying up the constructor, fixing\r
+// a bug in IASIOThiscallResolver::ASIOExit() and improving\r
