ZIP_SOURCE_ZIP(3) Library Functions Manual ZIP_SOURCE_ZIP(3)NAMEzip_source_zip - create data source from zip file
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
struct zip_source *
zip_source_zip(struct zip *archive, struct zip
*srcarchive, zip_uint64_t srcidx, zip_flags_t flags, zip_uint64_t
start, zip_int64_t len);
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.
ERRORSzip_source_zip() fails if:
[ZIP_ER_CHANGED] Unchanged data was requested, but it is not
available.
[ZIP_ER_INVAL] srcarchive, srcidx, start, or len are invalid.
[ZIP_ER_MEMORY] Required memory could not be allocated.
Additionally, it can return all error codes from zip_stat_index() and
zip_fopen_index().
