*
* Structure: H5FD_ros3_fapl_t
*
* Purpose:
*
* H5FD_ros3_fapl_t is a public structure that is used to pass S3
* authentication data to the appropriate S3 VFD via the FAPL. A pointer
* to an instance of this structure is a parameter to H5Pset_fapl_ros3()
* and H5Pget_fapl_ros3().
*
*
*
* `version` (int32_t)
*
* Version number of the H5FD_ros3_fapl_t structure. Any instance passed
* to the above calls must have a recognized version number, or an error
* will be flagged.
*
* This field should be set to H5FD_CURR_ROS3_FAPL_T_VERSION.
*
* `authenticate` (hbool_t)
*
* Flag TRUE or FALSE whether or not requests are to be authenticated
* with the AWS4 algorithm.
* If TRUE, `aws_region`, `secret_id`, and `secret_key` must be populated.
* If FALSE, those three components are unused.
*
* `aws_region` (char[])
*
* String: name of the AWS "region" of the host, e.g. "us-east-1".
*
* `secret_id` (char[])
*
* String: "Access ID" for the resource.
*
* `secret_key` (char[])
*
* String: "Secret Access Key" associated with the ID and resource.
