NAME
IO::Seekable - supply seek based methods for I/O objects
SYNOPSIS
use IO::Seekable;
package IO::Something;
@ISA = qw(IO::Seekable);
DESCRIPTION
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 the perlfunc 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
