- IO::Seekable - supply seek based methods for I/O objects

- IO::Seekable does not have a constuctor of its own as is
- intended to be inherited by other IO::Handle based objects.
- It provides methods which allow seeking of the file
- descriptors.
-
- If the C functions _f_g_e_t_p_o_s() and _f_s_e_t_p_o_s() are available,
- then IO::File::getpos returns an opaque value that
- represents the current position of the IO::File, and
- IO::File::setpos uses that value to return to a previously
- visited position.
-
- See the _p_e_r_l_f_u_n_c manpage for complete descriptions of each
- of the following supported IO::Seekable methods, which are
- just front ends for the corresponding built-in functions:
-
- seek
- tell

- _p_e_r_l_o_p manpage, the _I_O::_H_a_n_d_l_e manpage the _I_O::_F_i_l_e manpage
