18 The function zip_source_zip creates a zip source from a file in a zip
19 archive. The srcarchive argument is the (open) zip archive containing
20 the source zip file at index srcidx. len bytes from offset start will
21 be used in the zip_source. If len is 0 or -1, the rest of the file,
22 starting from start, is used. If start is zero and len is -1, the
23 whole file will be copied without decompressing it.
24
25 Supported flags are:
26
27 ZIP_FL_UNCHANGED Try to get the original data without any
28 changes that may have been made to
29 srcarchive after opening it.
30
31 ZIP_FL_RECOMPRESS When adding the data from srcarchive, re-
32 compress it using the current settings
33 instead of copying the compressed data.
34
36 Upon successful completion, the created source is returned. Otherwise,
37 NULL is returned and the error code in archive is set to indicate the
38 error.
