Move to new file position. Argument \var{offset} is a byte count. Optional
argument \var{whence} defaults to \code{0} (offset from start of file,
offset should be \code{>= 0}); other values are \code{1} (move relative to
current position, positive or negative), and \code{2} (move relative to end
of file, usually negative, although many platforms allow seeking beyond

of file; offset is usually negative, although many platforms allow seeking beyond
the end of a file).
Note that seeking of bz2 files is emulated, and depending on the parameters
