IOCTL_CDROM_RESUME_AUDIO IOCTL

Description

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

Parameters

Major code

Input buffer

None.

Input buffer length

None.

Output buffer

None.

Output buffer length

None.

Input/output buffer

Input/output buffer length

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.
