__stdcall STARBURN_IMPEX_API EXCEPTION_NUMBER StarBurn_CdvdBurnerGrabber_VerifyFile(IN PVOID p__PVOID__CdvdBurnerGrabber, OUT PCHAR p__PCHAR__ExceptionText, IN ULONG p__ULONG__ExceptionTextSizeInUCHARs, OUT PULONG p__PULONG__SystemError, OUT PCDB_FAILURE_INFORMATION p__PCDB_FAILURE_INFORMATION, IN PCHAR p__PCHAR__ImageFileName, IN LONG p__LONG__StartingLBA, OUT PLONG p__PLONG__FailedLBA, IN ULONG p__ULONG__ReportDelayInLBs);
Parameters | Description |
IN PVOID p__PVOID__CdvdBurnerGrabber | Pointer to the CdvdBurnerGrabber object that toolkit allocated before. |
OUT PCHAR p__PCHAR__ExceptionText | Pointer to array of CHARs that will be used to store formatted exception description message. |
IN ULONG p__ULONG__ExceptionTextSizeInUCHARs | Size of the array of CHARs used to be formatted exception message storage. |
OUT PULONG p__PULONG__SystemError | Pointer to ULONG that will contain the system error (if some will occur). |
OUT PCDB_FAILURE_INFORMATION p__PCDB_FAILURE_INFORMATION | Pointer to CDB_FAILURE_INFORMATION that will be filled with apropriate values. |
IN PCHAR p__PCHAR__ImageFileName | Pointer to image file name we'll open and read from to compare the data with recorded disc. |
IN LONG p__LONG__StartingLBA | LBA (logical block address) used to start recording from. |
OUT PLONG p__PLONG__FailedLBA | Pointer to the variable to contain failed LBA (number of sector failed verification process). |
IN ULONG p__ULONG__ReportDelayInLBs | Number of logical blocks verified before progress callback would be called. |
Execution status. EN_SUCCESS if the operation completed successfuly. If the exception number will be EN_SYSTEM_CALL_FAILED, variable that SystemError points to will be filled with system error. If something other then EN_SUCCESS will be returned buffer that ExceptionText will point to will be filled with formatted exception message. If the exception number will be EN_SCSI_CDB_FAILED, CDB_FAILURE_INFORMATION will be filled with apropriate values (CDB that faled, CDB size, SCSI sense data, SCSI sense data size, SCSI transport, device and host adapter status codes).
This function verifies recorded file system image on CD/DVD/Blu-Ray/HD-DVD burner device object used for this particular image recording (or maybe other image). This information can be used to be sure recorded disc is readable and really contains recorded information.
Please see the TrackAtOnceFromFile and VerifyFile samples that will demonstrate how ISO9660 or Joliet file system image can be burn on the CD/DVD/Blu-Ray/HD-DVD media and how StarBurn_CdvdBurnerGrabber_VerifyFile can be used for verification of the recorded content.
This example allocates CdvdBurnerGrabber object, burns image "IMAGE.ISO", verifies it and destroys the device object after it's not needed any more.
