ZIP_CLOSE(3)

ZIP_CLOSE(3) | Library Functions Manual | ZIP_CLOSE(3)

# NAME

`zip_close` —
close zip archive

# LIBRARY

libzip (-lzip)

# SYNOPSIS

`#include <zip.h>`

int
`zip_close`(zip_t *archive);

# DESCRIPTION

The `zip_close`() function writes any changes made to archive to disk. If archive contains no files, the file is completely removed (no empty archive is written), unless the archive flag `ZIP_AFL_CREATE_OR_KEEP_FILE_FOR_EMPTY_ARCHIVE` is set. If successful, archive is freed. Otherwise archive is left unchanged and must still be freed.

To close and free a zip archive without saving changes, use zip_discard(3).

Progress updates for GUIs can be implemented using zip_register_progress_callback_with_state(3). Cancelling the write of an archive during `zip_close` can be implemented using zip_register_cancel_callback_with_state(3).

# RETURN VALUES

Upon successful completion 0 is returned. Otherwise, -1 is returned and the error code in archive is set to indicate the error.

# ERRORS

`zip_close`() will fail if:

[`ZIP_ER_EOF`]
  Unexpected end-of-file found while reading from a file.
[`ZIP_ER_INTERNAL`]
  The callback function of an added or replaced file returned an error but failed to report which.
[`ZIP_ER_INVAL`]
  The path argument is `NULL`.
[`ZIP_ER_MEMORY`]
  Required memory could not be allocated.
[`ZIP_ER_NOZIP`]
  File is not a zip archive.
[`ZIP_ER_READ`]
  A file read failed.
[`ZIP_ER_RENAME`]
  A temporary file could not be renamed to its final name.
[`ZIP_ER_SEEK`]
  A file seek failed.
[`ZIP_ER_TMPOPEN`]
  A temporary file could not be created.
[`ZIP_ER_WRITE`]
  A file write failed.
[`ZIP_ER_ZLIB`]
  An error occurred while (de)compressing a stream with zlib(3).

Additionally, any errors returned by the callback function for added or replaced files will be passed back.

# CAVEATS

Please note that all indices, zip_stat(3) information and other data about the archive is invalid after `zip_close`. When you open the same file again, it will be a completely new zip_t structure.
