ZIP_GET_ARCHIVE_COMMENT(3) | Library Functions Manual | ZIP_GET_ARCHIVE_COMMENT(3)

# 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.
`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.
