| .SH "DESCRIPTION" |
| The function |
| \fBzip_source_file\fR() |
| creates a zip source from a file. |
| \fBzip_source_file\fR() |
| opens |
| \fIfname\fR |
| and reads |
| \fIlen\fR |
| bytes from offset |
| \fIstart\fR |
| from it. |
| If |
| \fIlen\fR |
| is 0 or \-1, the whole file (starting from |
| \fIstart\fR) |
| is used. |
| .PP |
| The fie is opened and read when the data from the source is used, usually by |
| \fBzip_close\fR(). |
| .SH "RETURN VALUES" |
| Upon successful completion, the created source is returned. |
| Otherwise, |
| \fRNULL\fR |
| is returned and the error code in |
| \fIarchive\fR |
| is set to indicate the error. |
