ZIP_GET_ARCHIVE_COMMENT(3) FreeBSD Library Functions Manual
NAME
zip_get_archive_comment - get zip archive comment
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
const char *
zip_get_archive_comment(zip_t *archive, int *lenp, zip_flags_t flags);
DESCRIPTION
The zip_get_archive_comment() function returns the comment for the entire
zip archive. The return value is in UTF-8 encoding unless ZIP_FL_ENC_RAW
was specified (see below). This pointer should not be modified or
free(3)'d, and becomes invalid when archive is closed. If lenp is not
NULL, the integer to which it points will be set to the length of the
comment. If flags is set to ZIP_FL_UNCHANGED, the original unchanged
comment is returned.
Additionally, the following flags are supported:
ZIP_FL_ENC_RAW Return the unmodified archive comment as it is
in the ZIP archive.
ZIP_FL_ENC_GUESS (Default.) Guess the encoding of the archive
comment in the ZIP archive and convert it to
UTF-8, if necessary. (Only CP-437 and UTF-8
are recognized.)
ZIP_FL_ENC_STRICT Follow the ZIP specification for file names
and extend it to the archive comment, thus
also expecting it in CP-437 encoding. Convert
it to UTF-8.
Note: ASCII is a subset of both CP-437 and UTF-8.
RETURN VALUES
Upon successful completion, a pointer to the comment is returned, or NULL
if there is no comment.

HISTORY
zip_get_archive_comment() was added in libzip 0.7. In libzip 0.11 the
type of flags was changed from int to zip_flags_t.
