Hi,
I would like to know if it's possible to append data into a variable, rather than into a file. Although I can write information into a temporary file in /tmp, I'd rather if possible write into a variable, as I don't like the idea that should my script fail, I'll be polluting the server with...

ARCHIVE_WRITE_FORMAT(3) BSD Library Functions Manual ARCHIVE_WRITE_FORMAT(3)
NAME
archive_write_set_format_cpio, archive_write_set_format_pax, archive_write_set_format_pax_restricted, archive_write_set_format_shar,
archive_write_set_format_shar_dump, archive_write_set_format_ustar -- functions for creating archives
LIBRARY
Streaming Archive Library (libarchive, -larchive)
SYNOPSIS
#include <archive.h>
int
archive_write_set_format_cpio(struct archive *);
int
archive_write_set_format_pax(struct archive *);
int
archive_write_set_format_pax_restricted(struct archive *);
int
archive_write_set_format_shar(struct archive *);
int
archive_write_set_format_shar_dump(struct archive *);
int
archive_write_set_format_ustar(struct archive *);
DESCRIPTION
These functions set the format that will be used for the archive.
The library can write POSIX octet-oriented cpio format archives, POSIX-standard ``pax interchange'' format archives, traditional ``shar'' ar-
chives, enhanced ``dump'' shar archives that store a variety of file attributes and handle binary files, and POSIX-standard ``ustar'' ar-
chives. The pax interchange format is a backwards-compatible tar format that adds key/value attributes to each entry and supports arbitrary
filenames, linknames, uids, sizes, etc. ``Restricted pax interchange format'' is the library default; this is the same as pax format, but
suppresses the pax extended header for most normal files. In most cases, this will result in ordinary ustar archives.
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.
