DESCRIPTION
The function
zip_source_zip
creates 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.len
bytes from offset
start
will be used in the zip_source.
If
len
is 0 or -1, the rest of the file, starting from
start,
is used.
If
start
is zero and
len
is -1, the whole file will be copied without decompressing it.
Supported flags are:
ZIP_FL_UNCHANGED
Try to get the original data without any changes that may have been
made to
srcarchive
after opening it.
ZIP_FL_RECOMPRESS
When adding the data from
srcarchive,
re-compress it using the current settings instead of copying the
compressed data.
RETURN VALUES
Upon successful completion, the created source is returned.
Otherwise,
NULL
is returned and the error code in
archive
is set to indicate the error.
