zip_source_zip_file
() and
zip_source_zip_file_create
() create a zip source from
a file in a zip archive. The srcarchive argument is the
(open) zip archive containing the source zip file at index
srcidx. length bytes from offset
start will be used in the zip_source. If
length is -1, the rest of the file, starting from
start, is used.
If you intend to copy a file from one archive to another, using
the flag ZIP_FL_COMPRESSED
is more efficient, as it
avoids recompressing the file data.
Supported flags are:
ZIP_FL_COMPRESSED
ZIP_FL_ENCRYPTED
ZIP_FL_COMPRESSED
.) This is only supported if the
complete file data is requested (start == 0 and
length == -1). Default is decrypted.ZIP_FL_UNCHANGED
NULL
is returned and the error code in
archive or error is set to
indicate the error.

zip_source_zip_file_create
() fail if:
