NAME

zip_file_add, zip_file_replaceadd file to zip archive or replace file in zip archive

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).

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]

[ZIP_ER_INVAL]
source or name are NULL, or index is invalid.
