DESCRIPTION

22     The functions zip_source_win32handle() and
23     zip_source_win32handle_create() create a zip source from a Windows file
24     handle.  They open fname and read len bytes from offset start from it.
25     If len is 0 or -1, the whole file (starting from start) is used.
26
27     If the file supports seek, the source can be used to open a zip archive
28     from.
29
30     The file is opened and read when the data from the source is used, usu‐
31     ally by zip_close() or zip_open_from_source().
32

RETURN VALUES

34     Upon successful completion, the created source is returned.  Otherwise,
35     NULL is returned and the error code in archive or error is set to indi‐
36     cate the error.
