the file descriptors. Has no constructor.

package IO::XXX;
@ISA = qw(IO::Seekable);

Frontend for the corresponding built-in seek
function, which sets a filehandle's position in the
file. Takes the following arguments:
offset
The offset where you want to set the position.whence
The position in the file that the offset is relative to. Possible
values are: 0 for the beginning of the file,
1 for the current position, or
2 for end of file. May also be expressed as the
following constants, which are exported:
SEEK_SET
Beginning of fileSEEK_CUR
Current positionSEEK_END
