NAME

     zip_file_get_comment — get comment for file in zip

LIBRARY

     libzip (-lzip)

SYNOPSIS

     #include <zip.h>

     const char *
     zip_file_get_comment(zip_t *archive, zip_uint64_t index, zip_uint32_t *lenp,
         zip_flags_t flags);

DESCRIPTION

     The zip_file_get_comment() function returns the comment for the file at position index in
     the zip archive.  The name 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 comment as it is in the ZIP archive.

           ZIP_FL_ENC_GUESS     (Default.)  Guess the encoding of the 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 file
                                comments, expecting them to be encoded in CP-437 in the ZIP
                                archive (except if it is a UTF-8 comment from the special extra
                                field).  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.  In case of an error, NULL is returned and the error code in archive is set to
     indicate the error.

ERRORS

     zip_file_get_comment() fails if:

     [ZIP_ER_INVAL]     index is not a valid file index in archive.
