Stream local file using Aws::FStream with specific offset and byte length

[mbutkovski]

Is there an option to stream a local file to AWS using Aws::S3::S3Client with specific offset and byte length (without reading the file into local buffer)?

In general : streaming whole file using Aws::FStream and uploading buffer using Aws::StringStream - all works.

But I need to stream file with offset and specific byte length.
This is what I've tried using Minio server:

PutObjectRequest request;
request.WithBucket("bucket_name").WithKey("remotePath");
std::shared_ptr<Aws::IOStream> data = Aws::MakeShared<Aws::FStream>(ALLOC_TAG, "localPath", std::ios_base::in | std::ios_base::binary);
request.SetBody(data);
request.SetContentLength(sizeInBytes);
data->seekg(offsetInBytes, std::ios_base::beg);
PutObjectOutcome outcome = pS3Client->PutObject(request);
if (outcome.IsSuccess() == false)
 //print some error

It doesn't work.
Call to Aws::S3::S3Client::PutObject fails. The failure message is:

Encountered network error when sending http request

Minio server prints the error message :

Error: read tcp 127.0.0.1:9000->127.0.0.1:49811: wsarecv: An existing connection was forcibly closed by the remote host. (*net.OpError)
