# 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
