The zip_source_window_create() function create a zip
source from an underlying zip source, restricting access to a particular
window starting at byte start and having size
len. If len is -1, the window
spans to the end of the underlying source.
Upon successful completion, the created source is returned. Otherwise,
NULL is returned and the error code in
error is set to indicate the error.
zip_source_window_create() fails if:
- [
ZIP_ER_INVAL]
- src is
NULL; there is an
integer overflow adding start and
len; or len is less than
-1.
- [
ZIP_ER_MEMORY]
- Required memory could not be allocated.
zip_source_window_create() was added in libzip 1.8.0.
