One way is via pax. I created directory called tartest and populated it with a few files. The I did:
tar cvf tartest.tar tartest
This results in a tar archive with files in a directory called tartest. I can restore this with pax via:
pax -r -dv -f tartest.tar
But if I want to restore the files directly into my current directory, I can do:
pax -r -f tartest.tar -s'/tartest\///'
Before you try something like that, do this... "pax -dv -f tartest.tar" is like "tar tvf tartest.tar". It just lists the contents of the tar archive. Now do:
pax -dv -f tartest.tar -s'/tartest\///p'
and look at the results. This way you can be sure that you have the -s argument right before you try the restore.

I have a tar file that contains a number of files that are stored in different directories.

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.
