◆ sound_oss_sysinfo()
| void sound_oss_sysinfo | ( | oss_sysinfo * | si | ) |
Handle OSSv4 SNDCTL_SYSINFO ioctl.
- Parameters
-
si Pointer to oss_sysinfo struct where information about the sound subsystem will be written/copied.
This routine returns information about the sound system, such as the current OSS version, number of audio, MIDI, and mixer drivers, etc. Also includes a bitmask showing which of the above types of devices are open (busy).
- Note
- Calling threads must not hold any snddev_info or pcm_channel locks.
- Todo:
- Collect num{midis,timers}.
Need access to sound/midi/midi.c::midistat_lock in order to safely touch midi_devices and get a head count of, well, MIDI devices. midistat_lock is a global static (i.e., local to midi.c), but midi_devices is a regular global; should the mutex be publicized, or is there another way to get this information?
NB: MIDI/sequencer stuff is currently on hold.
- Todo:
- Fill in "busy devices" fields.
si->openedmidi = " MIDI devices
