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. + 2004-03-19 Pierre Humblet <pierre.humblet@ieee.org> Christopher Faylor <cgf@redhat.com> |
