b50bca981eThe fix for DEFINE_GUID that was recently added in pa_win_wdmks.c is also needed for the MSVC compiler. Latest versions of the compiler support the /Zc:preprocessor option which is conforming to C99 and later standards https://docs.microsoft.com/en-us/cpp/build/reference/zc-preprocessor?view=msvc-160 so it generates the exact same error as Clang (too many arguments error).

PortAudio - portable audio I/O library
PortAudio is a portable audio I/O library designed for cross-platform support of audio. It uses either a callback mechanism to request audio processing, or blocking read/write calls to buffer data between the native audio subsystem and the client. Audio can be processed in various formats, including 32 bit floating point, and will be converted to the native format internally.
Documentation:
- Documentation is available at http://www.portaudio.com/docs/
- Or at
/doc/html/index.htmlafter running Doxygen. - Also see
src/common/portaudio.hfor the API spec. - And see the
examples/andtest/directories for many examples of usage. (We suggestexamples/paex_saw.cfor an example.)
For information on compiling programs with PortAudio, please see the tutorial at:
http://portaudio.com/docs/v19-doxydocs/tutorial_start.html
We have an active mailing list for user and developer discussions. Please feel free to join. See http://www.portaudio.com for details.
Important Files and Folders:
include/portaudio.h = header file for PortAudio API. Specifies API.
src/common/ = platform independent code, host independent
code for all implementations.
src/os = os specific (but host api neutral) code
src/hostapi = implementations for different host apis
Host API Implementations:
src/hostapi/alsa = Advanced Linux Sound Architecture (ALSA)
src/hostapi/asihpi = AudioScience HPI
src/hostapi/asio = ASIO for Windows and Macintosh
src/hostapi/coreaudio = Macintosh Core Audio for OS X
src/hostapi/dsound = Windows Direct Sound
src/hostapi/jack = JACK Audio Connection Kit
src/hostapi/oss = Unix Open Sound System (OSS)
src/hostapi/wasapi = Windows Vista WASAPI
src/hostapi/wdmks = Windows WDM Kernel Streaming
src/hostapi/wmme = Windows MultiMedia Extensions (MME)
Test Programs:
test/pa_fuzz.c = guitar fuzz box
test/pa_devs.c = print a list of available devices
test/pa_minlat.c = determine minimum latency for your machine
test/paqa_devs.c = self test that opens all devices
test/paqa_errs.c = test error detection and reporting
test/patest_clip.c = hear a sine wave clipped and unclipped
test/patest_dither.c = hear effects of dithering (extremely subtle)
test/patest_pink.c = fun with pink noise
test/patest_record.c = record and playback some audio
test/patest_maxsines.c = how many sine waves can we play? Tests Pa_GetCPULoad().
test/patest_sine.c = output a sine wave in a simple PA app
test/patest_sync.c = test synchronization of audio and video
test/patest_wire.c = pass input to output, wire simulator
