IO::Seekable

IO::Seekable(3)        Perl Programmers Reference Guide        IO::Seekable(3)



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
