NEROAPI_API NERO_ISO_ITEM *NADLL_ATTR NeroImportDataTrack( NERO_DEVICEHANDLE pRecorder,
DWORD trackNumber,
void **ppCDStamp,
NERO_IMPORT_DATA_TRACK_INFO *pInfo,
DWORD flags,
NERO_IMPORT_DATA_TRACK_RESULT *result,
void *reserved); // Must be NULL

If you take a look at NeroAPI.h header file you will find a comment errors in the filesystem on the disc.
Again, you need to consult NeroAPI.h for the supported values. These are NIITEF_ flags.
DVD plus/minus rewritables don't have real sessions, just one track. In order to support multiple sessions, virtual multisession was introduced.
