I’m trying to learn how to use libzip to create a ZIP file with Visual Studio 2022 and C on Windows 11. When I’m finished, my file should have multiple files in multiple different folders. That’s my final goal. Right now, I just want to create a ZIP file, but the library is not helping me to use it correctly because it is not returning errors, even when it fails to do anything (detectable) that I’ve asked it to do. I’m not looking for help fixing my code (though I certainly won’t refuse it! [smile]), what I’m really trying to learn here is how to debug problems with a library that returns success even when it clearly fails.
