_CDROM_SIMPLE_OPC_INFO structure

Description

The CDROM_SIMPLE_OPC_INFO structure is the only input for the IOCTL_CDROM_SEND_OPC_INFORMATION I/O control code.

Members

`RequestType`

The request type defined in the CDROM_OPC_INFO_TYPE enumeration.

`Exclude0`

Exclude layer 0 from OPC.

`Exclude1`

Exclude layer 1 from OPC.

Remarks

The IOCTL_CDROM_SEND_OPC_INFORMATION IOCTL is a wrapper for the SEND OPC INFORMATION command of the Multimedia Commands (MMC) specification. The Exclude0 and Exclude1 fields of the CDROM_SIMPLE_OPC_INFO structure map directly to the corresponding SEND OPC INFORMATION fields.
