CDROM_SIMPLE_OPC_INFO structure (ntddcdrm.h)
The CDROM_SIMPLE_OPC_INFO structure is the only input for the IOCTL_CDROM_SEND_OPC_INFORMATION I/O control code.
Syntax
typedef struct _CDROM_SIMPLE_OPC_INFO {
CDROM_OPC_INFO_TYPE RequestType;
BOOLEAN Exclude0;
BOOLEAN Exclude1;
} CDROM_SIMPLE_OPC_INFO, *PCDROM_SIMPLE_OPC_INFO;
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.
