set zip archive comment
*archive, const char
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.
Upon successful completion 0 is returned. Otherwise, -1 is returned and the
error information in archive is set to indicate the
zip_set_archive_comment() fails if:
- 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.
- 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.
