== 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 == 

Detailed error codes and textual descriptions are available from the 

'''archive_errno'''() 

and 

'''archive_error_string'''() 

functions.
