ZIP_GET_ARCHIVE_COMMENT(3)                            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.
