IOCTL_CDROM_RESUME_AUDIO control code

Resumes a suspended audio operation. Obsolete, beginning with Windows Vista.

Input Parameters

None.

Output Parameters

None.

I/O Status Block

The Information field is set to zero. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_INVALID_DEVICE_REQUEST if audio is not currently suspended, 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.

Requirements

Version

Obsolete, beginning with Windows Vista.
