DESCRIPTION

The functions Fn zip_source_zip and Fn zip_source_zip_create are the obsolete versions of zip_source_zip_file3 or zip_source_zip_file_create3 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 Fn zip_source_zip and Fn zip_source_zip_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 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.

 

RETURN VALUES

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.
