ZIP_SOURCE_ZIP(3) Library Functions Manual ZIP_SOURCE_ZIP(3)

zip_source_zip, zip_source_zip_create — create data source from zip file (obsolete interface)

libzip (-lzip)

#include <zip.h>

zip_source_t *
zip_source_zip(zip_t *archive, zip_t *srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t start, zip_int64_t len);

zip_source_t *
zip_source_zip_create(zip_t *srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t start, zip_int64_t len, zip_error_t *error);

The functions () and () are the obsolete versions of zip_source_zip_file(3) or zip_source_zip_file_create(3) respectively. If you want to get the compressed data of the complete file, use

zip_source_zip_file(za, source_archive, source_index, ZIP_FL_COMPRESSED, 0, -1, NULL)

The functions () and () 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. 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:

Try to get the original data without any changes that may have been made to srcarchive after opening it.

Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive or error is set to indicate the error.

zip_source_zip() and zip_source_zip_create() fail if:

[]
Unchanged data was requested, but it is not available.
[]
srcarchive, srcidx, start, or len are invalid.
[]
Required memory could not be allocated.
Additionally, it can return all error codes from zip_stat_index() and zip_fopen_index().

libzip(3), zip_file_add(3), zip_file_replace(3), zip_source(3)

zip_source_zip() was added in libzip 1.0. zip_source_zip_create() was added in libzip 1.8.0. Both were deprecated in libzip 1.10.0. Use zip_source_zip_file() or zip_source_zip_file_create() instead.
