NAME
zip_source_zip — 
create data source
  from zip file
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);
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.
ERRORS
zip_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
