2004-03-24update copyright. Minor reformatting.Christopher Faylor1-4/+6
2004-03-24 * fhandler_dsp.cc (fhandler_dev_dsp::write): Remove typeCorinna Vinschen2-3/+12
cast from argument to audio_out_->parsewav() to make reference work properly. Now .wav file headers are properly discarded.
2004-03-23white space fixupChristopher Faylor1-3/+3
2004-03-23 * fhandler_disk_file.cc (fhandler_base::fstat_fs): Use createdCorinna Vinschen2-3/+16
handle regardless of nohandle state. Clean up afterwards.
2004-03-23 * autoload.cc: Load eight more functions for waveIn support.Corinna Vinschen4-344/+1190
* fhandler.h (class fhandler_dev_dsp): Add class Audio, class Audio_in and class Audio_out members and audio_in_, audio_out_ pointers so that future changes are restricted to file fhandler_dsp.cc. * fhandler_dsp.cc (fhandler_dev_dsp::Audio): Add this class to treat things common to audio recording and playback. Add more format conversions. (fhandler_dev_dsp::Audio::queue): New queues for buffer management to fix incomplete cleanup of buffers passed to the wave device. (fhandler_dev_dsp::Audio_in): New, added class to implement audio recording. (fhandler_dev_dsp::Audio_out): Rework to use functionality provided by fhandler_dev_dsp::Audio. Allocate memory audio buffers late, just before write. (fhandler_dev_dsp::Audio_out::start): Size of wave buffer allocated here depends on audio rate/bits/channels. (fhandler_dev_dsp::Audio_in::start): Ditto. (fhandler_dev_dsp::setupwav): Replaced by following function. (fhandler_dev_dsp::Audio_out::parsewav): Does not setup wave device any more. Discard wave header properly. (fhandler_dev_dsp::open): Add O_RDONLY and_RDWR as legal modes. Protect against re-open. Activate fork_fixup. (fhandler_dev_dsp::ioctl): Protect against actions when audio is active. SNDCTL_DSP_GETFMTS only returns formats supported by mmsystem wave API, not all supported formats. SNDCTL_DSP_GETBLKSIZE result now depends on current audio format. (fhandler_dev_dsp::fixup_after_fork): Call fork_fixup for the Audio classes to let them duplicate the CRITICAL_SECTION.
