IOCTL_CDROM_SEEK_AUDIO_MSF IOCTL (ntddcdrm.h)
Moves the heads to the specified MSF on the media. Obsolete, beginning with Windows Vista.
Major code
Input buffer
The buffer at Irp->AssociatedIrp.SystemBuffer contains the CDROM_SEEK_AUDIO_MSF specification.
Input buffer length
Parameters.DeviceIoControl.InputBufferLength indicates the size, in bytes, of the buffer.
Output buffer
None.
Output buffer length
None.
Status block
The Information field is set to zero. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_BUFFER_TOO_SMALL, STATUS_INVALID_DEVICE_REQUEST, STATUS_IO_DEVICE_ERROR, STATUS_NO_MEDIA_IN_DEVICE, STATUS_DEVICE_NOT_READY, STATUS_IO_TIME_OUT, or STATUS_VERIFY_REQUIRED.
Remarks
Beginning with Windows Vista, CDROM class drivers do not use this IOCTL. Prior to Windows Vista, this IOCTL was used for audio playback on older CD-ROM drives that supported direct audio output in hardware.
Client applications should use the Media Control Interface (MCI) API rather than issuing this IOCTL.
