| .SH "DESCRIPTION" |
| The functions |
| \fBzip_source_win32handle\fR() |
| and |
| \fBzip_source_win32handle_create\fR() |
| create a zip source from a Windows file handle. |
| They open |
| \fIfname\fR |
| and read |
| \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 |
| If the file supports seek, the source can be used to open a zip archive from. |
| .PP |
| The file is opened and read when the data from the source is used, usually by |
| \fBzip_close\fR() |
| or |
| \fBzip_open_from_source\fR(). |
| .SH "RETURN VALUES" |
| Upon successful completion, the created source is returned. |
| Otherwise, |
| \fRNULL\fR |
| is returned and the error code in |
| \fIarchive\fR |
| or |
| \fIerror\fR |
| is set to indicate the error. |
| .SH "ERRORS" |
| \fBzip_source_w32handle\fR() |
| and |
| \fBzip_source_w32handle_create\fR() |
| fail if: |
| .TP 19n |
| [\fRZIP_ER_INVAL\fR] |
| \fIfname\fR, |
| \fIstart\fR, |
| or |
| \fIlen\fR |
| are invalid. |
| .TP 19n |
| [\fRZIP_ER_MEMORY\fR] |
| Required memory could not be allocated. |
| .TP 19n |
| [\fRZIP_ER_OPEN\fR] |
| Opening |
| \fIfname\fR |
| failed. |
