LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
zip_int64_t
zip_file_add(
zip_t
  *archive, 
const char
  *name, 
zip_source_t
  *source, 
zip_flags_t
  flags);
int
zip_file_replace(
zip_t
  *archive, 
zip_uint64_t
  index, 
zip_source_t
  *source, 
zip_flags_t
  flags);
DESCRIPTION
The function 
zip_file_add() adds a file to a zip archive,
  while 
zip_file_replace() replaces an existing file in a zip
  archive. The argument 
archive specifies the zip archive
  to which the file should be added. 
name is the file's
  name in the zip archive (for 
zip_file_add()), while
  
index specifies which file should be replaced (for
  
zip_file_replace()). The 
flags
  argument can be any combination of 
ZIP_FL_OVERWRITE
  with one of 
ZIP_FL_ENC_*:
  -  
-  
- ZIP_FL_OVERWRITE
- Overwrite any existing file of the same name. For
      zip_file_add only.
-  
-  
- ZIP_FL_ENC_GUESS
- Guess encoding of name
    (default).
-  
-  
- ZIP_FL_ENC_UTF_8
- Interpret name as UTF-8.
-  
-  
- ZIP_FL_ENC_CP437
- Interpret name as code page 437
      (CP-437).
The data is obtained from the 
source argument, see
  
zip_source(3).
NOTE:
  
zip_source_free(3) should not be
  called on a 
source after it was used successfully in a
  
zip_file_add or 
zip_file_replace call.
RETURN VALUES
Upon successful completion, 
zip_file_add() returns the index
  of the new file in the archive, and 
zip_file_replace()
  returns 0. Otherwise, -1 is returned and the error code in
  
archive is set to indicate the error.
EXAMPLES
zip_source_t *s; 
const char buf="teststring"; 
 
if ((s=zip_source_buffer(archive, buffer, sizeof(buf), 0)) == NULL || 
    zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) < 0) { 
    zip_source_free(s); 
    printf("error adding file: %s\n", zip_strerror(archive)); 
}
 
ERRORS
zip_file_add() and 
zip_file_replace() fail
  if:
  -  
-  
- [ZIP_ER_EXISTS]
- There is already a file called name
      in the archive. (Only applies to zip_file_add(), and
      only if ZIP_FL_OVERWRITEis not provided).
-  
-  
- [ZIP_ER_INVAL]
- source or name
      are NULL, or index is
      invalid.
-  
-
