Uploading Buffer Data

UploadBuffer()

This section describes how to upload buffer data to OBS. During the buffer upload, threads are blocked. They are not blocked until the buffer data is uploaded successfully. You can configure the target OBS bucket on the HiLens console. For details, see the "Configuring the Data Storage Location" section in HiLens User Guide.

API calling
HiLensEC hilens::UploadBuffer(const std::string & key, const unsigned char * buffer, const unsigned char * buffer, size_t bufferSize, const std::string & mode)
