Debian                                          December 18, 2017                     ZIP_SET_ARCHIVE_COMMENT(3)

       The  zip_set_archive_comment()  function sets the comment for the entire zip archive.  If comment is NULL
       and len is 0, the archive comment will be removed.  comment must be encoded in ASCII or UTF-8.

zip_set_archive_comment() fails if:

       [ZIP_ER_INVAL]     len is less than 0 or longer than the maximum comment length in a zip file (65535), or
                          comment is not a valid UTF-8 encoded string.

       [ZIP_ER_MEMORY]    Required memory could not be allocated.

zip_set_archive_comment() was added in libzip 0.7.  In libzip 0.11 the type of len was changed  from  int
       to zip_uint16_t.
