# DESCRIPTION

`archive_write_add_filter_bzip2`(), `archive_write_add_filter_compress`(), `archive_write_add_filter_grzip`(), `archive_write_add_filter_gzip`(), `archive_write_add_filter_lrzip`(), `archive_write_add_filter_lz4`(), `archive_write_add_filter_lzip`(), `archive_write_add_filter_lzma`(), `archive_write_add_filter_lzop`(), `archive_write_add_filter_xz`(), `archive_write_add_filter_zstd`(),
  The resulting archive will be compressed as specified. Note that the compressed output is always properly blocked.
`archive_write_add_filter_b64encode`(), `archive_write_add_filter_uuencode`(),
  The output will be encoded as specified. The encoded output is always properly blocked.
`archive_write_add_filter_none`()
  This is never necessary. It is provided only for backwards compatibility.
`archive_write_add_filter_program`()
  The archive will be fed into the specified compression program. The output of that program is blocked and written to the client write callbacks.

# RETURN VALUES

These functions return `ARCHIVE_OK` on success, or `ARCHIVE_FATAL`.

# ERRORS
