| .SH "DESCRIPTION" |
| The |
| \fBzip_source_window_create\fR() |
| function create a zip source from an underlying zip source, |
| restricting access to a particular window starting at byte |
| \fIstart\fR |
| and having size |
| \fIlen\fR. |
| If |
| \fIlen\fR |
| is \-1, the window spans to the end of the underlying source. |
| .SH "RETURN VALUES" |
| Upon successful completion, the created source is returned. |
| Otherwise, |
| \fRNULL\fR |
| is returned and the error code in |
| \fIerror\fR |
| is set to indicate the error. |
| .SH "ERRORS" |
| \fBzip_source_window_create\fR() |
| fails if: |
| .TP 19n |
| [\fRZIP_ER_INVAL\fR] |
| \fIsrc\fR |
| is |
| \fRNULL\fR; |
| there is an integer overflow adding |
| \fIstart\fR |
| and |
