Update of /cvsroot/pywin32/pywin32/com/win32comext/directsound/test In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv6405/com/win32comext/directsound/test Added Files: 01-Intro.wav ds_test.py Log Message: Added (some) DirectSound support. The bulk is in com/win32comext/directsound, including a test directory with a sample soundfile and a unittest-based test script. Supported are: - IDirectSound - IDirectSoundBuffer - IDirectSoundNotify. Also added support for: - WAVEFORMATEX (in PyWinTypes) - DSBUFFERDESC - DSBCAPS - DSCAPS - various constants used in these structures Missing is: - IDirectSoundCapture - complete documentation --- NEW FILE: ds_test.py --- import unittest import struct import sys import pywintypes import win32event #
