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 constructor of its own as it 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




SEE ALSO
     the perlfunc manpage, the section on I/O Operators in the
     perlop manpage, the IO::Handle manpage the IO::File manpage
