HDF5 File Access Property List Interface
The functions, macros, and subroutines listed here are used to
manipulate file access property lists (fapl) objects in various
ways.
H5Pset_fapl_ros3 ( h5plist, s3credentials = NULL)
h5plist |
An object of class |
s3credentials |
Either |
To access files in a private Amazon S3 bucket you will need to provide three
additional details: The AWS region where the files are hosted, your AWS access
key ID, and your AWS secret access key. More information on how to obtain AWS
access keys can be found at https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys.
These are provided as a list to the s3credentials argument. If you
are accessing public data this argument should be NULL.
See https://portal.hdfgroup.org/display/HDF5/File+Access+Properties for further details. See H5P for documentation of more functions to manupulate property lists of other property list classes.
The functions return the standard return value from their respective C-functions.
