LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
zip_source_t *
zip_source_file(
zip_t
  *archive, 
const char
  *fname, 
zip_uint64_t
  start, 
zip_int64_t
  len);
zip_source_t *
zip_source_file_create(
const
  char *fname,

  start, 
zip_int64_t
  len, 
zip_error_t
  *error);
DESCRIPTION
The functions 
zip_source_file() and
  
zip_source_file_create() create a zip source from a file.
  They open 
fname and read 
len bytes
  from offset 
start from it. If 
len
  is 0 or -1, the whole file (starting from 
start) is
  used.
If the file supports seek, the source can be used to open a zip archive from.
The file is opened and read when the data from the source is used, usually by
  
zip_close() or 
zip_open_from_source().
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_file() and
  
zip_source_file_create() fail if:
  -  
-  
- [ZIP_ER_INVAL]
- fname, start,
      or len are invalid.
-  
-  
- [ZIP_ER_MEMORY]
- Required memory could not be allocated.
-  
-  
- [ZIP_ER_OPEN]
- Opening fname failed.
