| .SH "DESCRIPTION" |
| The |
| \fBzip_file_set_comment\fR() |
| function sets the comment for the file at position |
| \fIindex\fR |
| in the zip archive to |
| \fIcomment\fR |
| of length |
| \fIlen\fR. |
| If |
| \fIcomment\fR |
| is |
| \fRNULL\fR |
| and |
| \fIlen\fR |
| is 0, the file comment will be removed. |
| The |
| \fIflags\fR |
| argument can be any of: |
| .TP 22n |
| \fRZIP_FL_ENC_GUESS\fR |
| Guess encoding of |
| \fIcomment\fR |
| (default). |
| (Only CP-437 and UTF-8 are recognized.) |
| .TP 22n |
| \fRZIP_FL_ENC_UTF_8\fR |
| Interpret |
| \fIcomment\fR |
| as UTF-8. |
| .TP 22n |
| \fRZIP_FL_ENC_CP437\fR |
| Interpret |
| \fIcomment\fR |
| as code page 437 (CP-437). |
| .SH "RETURN VALUES" |
| Upon successful completion 0 is returned. |
| Otherwise, \-1 is returned and the error information in |
| \fIarchive\fR |
| is set to indicate the error. |

| .TP 19n |
| [\fRZIP_ER_INVAL\fR] |
| \fIindex\fR |
| is not a valid file index in |
| \fIarchive\fR, |
| or |
| \fIlen\fR |
| is less than 0 or longer than the maximum comment length in a zip file |
| (65535), or |
| \fIcomment\fR |
| is not a valid UTF-8 encoded string. |
| .TP 19n |
| [\fRZIP_ER_MEMORY\fR] |
| Required memory could not be allocated. |
