# NAME

zip_file_add, zip_file_replace — add 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).
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_OVERWRITE` is not provided).
[`ZIP_ER_INVAL`]
  source or name are `NULL`, or index is invalid.
[`ZIP_ER_MEMORY`]
  Required memory could not be allocated.
[`ZIP_ER_RDONLY`]
  Archive was opened in read-only mode.
