IO::Seekable - supply seek based methods for I/O objects
use IO::Seekable; package IO::Something; @ISA = qw(IO::Seekable);
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 fgetpos() and fsetpos() 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 perlfunc for complete descriptions of each of the following supported
IO::Seekable methods, which are just front ends for the corresponding built-in functions:
