Parameters

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.

Returns

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).

Description

This function releases the media inside the CD/DVD/Blu-Ray/HD-DVD device after the media was locked before.

Remarks

Please see the TrackAtOnceFromFile and TrackAtOnceFromTree sample that will demonstrate how ISO9660 or Joliet file system image can be burn on the CD/DVD/Blu-Ray/HD-DVD media. StarBurn_CdvdBurnerGrabber_Lock can be used to lock the CD/DVD/Blu-Ray/HD-DVD media to prevent media removal from the device while burning (or any I/O process) is in progress. StarBurn_CdvdBurnerGrabber_Release can be used to release (unlock) the media that was locked before.

Example

This example allocates CdvdBurnerGrabber object, locks it, releases (unlocks) and destroys the device object after it's not needed any more.
