Re: Read ZIP comments

I need to read ZIP file comments. The QzipZip() API

API
(https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/apis/qzipunzip.htm)
doesn't have the option to read them.

If I'm reading the description correctly, the QzipUnzip API doesn't _READ_ a ZIP ... it extracts files from a ZIP.

I wouldn't expect that API to care about ZIP comments.

I suspect you're looking for some kind of ZIP information API.

You might be able to roll your own using the information on this page: https://users.cs.jmu.edu/buchhofp/forensics/formats/pkzip.html

Alternatively, you might be able to use Java to extract information. https://docs.oracle.com/javase/6/docs/api/java/util/zip/package-summary.html
