Issues a READ_TOC_PMA_ATIP command to the device as defined in MMC-2/SFF-8020i.

Declaration

IOReturn (*ReadTableOfContents)(void *self, SCSICmdField1Bit MSF, SCSICmdField4Bit FORMAT, SCSICmdField1Byte TRACK_SESSION_NUMBER, void *buffer, SCSICmdField2Byte bufferSize, SCSITaskStatus *taskStatus, SCSI_Sense_Data *senseDataBuffer);

Parameters

self

Pointer to an MMCDeviceInterface for one IOService.

MSF

The MSF bit as defined in MMC-2/SFF-8020i.

FORMAT

The FORMAT field as defined in MMC-2/SFF-8020i.

TRACK_SESSION_NUMBER

The TRACK_SESSION_NUMBER field as defined in MMC-2/SFF-8020i.

buffer

Pointer to the buffer to be used for this function.

bufferSize

The size of the data transfer requested.

taskStatus

Pointer to a SCSITaskStatus to get the status of the SCSITask which was executed. Valid SCSITaskStatus values are defined in SCSITask.h

senseDataBuffer

Pointer to a buffer the size of the SCSI_Sense_Data struct found in SCSICmds_REQUEST_SENSE_Defs.h. The sense data is only valid if the SCSITaskStatus is kSCSITaskStatus_CHECK_CONDITION.

Return Value

Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService, kIOReturnNoMemory if a SCSITask couldn't be created, or kIOReturnExclusiveAccess if the device is already opened for exclusive access by another client.

Discussion

Once an MMCDeviceInterface is opened the client may send this command to read the table of contents from the media.
