C++

__fastcall Boolean Upload(const TStream AContent, AnsiString ABucket, AnsiString AKey, Boolean AUseTempFiles = False, TS3UploadPartBatchProgressCallback AOnProgress = null);

Parameters

Parameters	Description
ABucket: string	The name of a bucket to upload to.
AKey: string	An object key to use for the uploaded data.
AUseTempFiles: Boolean = False	Specifies whether temporary files should be used when performing multipart uploads. Using temporary files can reduce memory pressure when performing large uploads at the cost of storage space and disk I/O.
AOnProgress: TS3UploadPartBatchProgressCallback = nil	A callback providing progress updates.
AStream	A stream containing the part's content to upload.

Returns

A Boolean value indicating success (True) or failure (False) of the upload.

Example

// Create or load a stream of data to upload. var LStream := TMemoryStream.Create; var S3 := TS3Client.Create; var LUploader := TS3MultipartUploader.Create(S3) as IS3MultipartUploader; // Upload in 10 MegaByte parts. LUploader.PartSize := 10 * 1024 * 1024; LUploader.Upload( LStream, 'a-destination-bucket', 'a-destination-key' False, procedure(const AUploadId: string; APartNumber: Integer; APartSize, APartWriteCount, AOverallSize, AOverallWriteCount: Int64; var AAbort: Boolean) begin // Update your user interface with current progress. end );
