17 The zip_source_window_create() function create a zip source from an un‐
18 derlying zip source, restricting access to a particular window starting
19 at byte start and having size len. If len is -1, the window spans to the
20 end of the underlying source.

23 Upon successful completion, the created source is returned. Otherwise,
24 NULL is returned and the error code in error is set to indicate the er‐
25 ror.
