| .SH "SYNOPSIS" |
| #include <zip.h> |
| .PP |
| const char * |
| zip_get_archive_comment(struct zip *archive, int *lenp, zip_flags_t flags); |
| .SH "DESCRIPTION" |
| The |
| zip_get_archive_comment |
| function returns the comment for the entire zip archive. |
| The name is in UTF-8 encoding unless |
| \fBZIP_FL_ENC_RAW\fR |
| was specified (see below). |
| This pointer should not be modified or |
| free(3) |
| Ap d, |
| and becomes invalid when |
| \fBarchive\fR |
| is closed. |
| If |
| \fBlenp\fR |
| is not |
| \fBNULL,\fR |
| the integer to which it points will be set to the length of the |
| comment. |
| If |
| \fBflags\fR |
| is set to |
| \fBZIP_FL_UNCHANGED,\fR |
| the original unchanged comment is returned. |
| .PP |
| Additionally, the following flags are supported: |
| .RS |
| .TP 21 |
| \fBZIP_FL_ENC_RAW\fR |
| Return the unmodified archive comment as it is in the ZIP archive. |
| .TP 21 |
| \fBZIP_FL_ENC_GUESS\fR |
| (Default.) |
| Guess the encoding of the archive comment in the ZIP archive and convert it |
| to UTF-8, if necessary. |
| .TP 21 |
| \fBZIP_FL_ENC_STRICT\fR |
| 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. |
| .RE |
| .I Note: |
| ASCII is a subset of both CP-437 and UTF-8. |
| .SH "RETURN VALUES" |
| Upon successful completion, a pointer to the comment is returned, |
| or |
| \fBNULL\fR |
| if there is no comment. |
| .\" In case of an error, |
| .\" \fBNULL\fR |
| .\" is returned and the error code in |
| .\" \fBarchive\fR |
| .\" is set to indicate the error. |
