I downloaded and looked at the libs3 code , a library written for C / C ++ that interacts with Amazon S3. This library uses several concepts that I don’t quite like, so I wonder if people know about any textbooks or sample programs that use this library.
The only place I found reasonable examples was to study the header files for libs3 and view the source code for the s3.c application, which is now included in the library.
