ZIP_SOURCE_ZIP(3)          Library Functions Manual          ZIP_SOURCE_ZIP(3)

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

LIBRARY
     libzip (-lzip)

SYNOPSIS
     #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);

DESCRIPTION
     The functions zip_source_zip() and zip_source_zip_create() 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 zip_source_zip() and 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:
     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.

ERRORS
     zip_source_zip() and zip_source_zip_create() fail 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().

HISTORY
     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 instead.
