+.SH NAME
+IO::Seekable \- supply seek based methods for I/O objects
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 3
+\&    use IO::Seekable;
+\&    package IO::Something;
+\&    @ISA = qw(IO::Seekable);
+.Ve
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\f(CW\*(C`IO::Seekable\*(C'\fR does not have a constructor of its own as it is intended to
+be inherited by other \f(CW\*(C`IO::Handle\*(C'\fR based objects. It provides methods
+which allow seeking of the file descriptors.
+.ie n .IP $io\->getpos 4
+.el .IP \f(CW$io\fR\->getpos 4
+.IX Item "$io->getpos"
+Returns an opaque value that represents the current position of the
+IO::File, or \f(CW\*(C`undef\*(C'\fR if this is not possible (eg an unseekable stream such
+as a terminal, pipe or socket). If the \fBfgetpos()\fR function is available in
+your C library it is used to implements getpos, else perl emulates getpos
+using C's \fBftell()\fR function.
+.ie n .IP $io\->setpos 4
+.el .IP \f(CW$io\fR\->setpos 4
+.IX Item "$io->setpos"
+Uses the value of a previous getpos call to return to a previously visited
+position. Returns "0 but true" on success, \f(CW\*(C`undef\*(C'\fR on failure.
+.PP
+See perlfunc for complete descriptions of each of the following
+supported \f(CW\*(C`IO::Seekable\*(C'\fR methods, which are just front ends for the
+corresponding built-in functions:
+.ie n .IP "$io\->seek ( POS, WHENCE )" 4
+.el .IP "\f(CW$io\fR\->seek ( POS, WHENCE )" 4
+.IX Item "$io->seek ( POS, WHENCE )"
+Seek the IO::File to position POS, relative to WHENCE:
+.RS 4
+.IP "WHENCE=0 (SEEK_SET)" 8
+.IX Item "WHENCE=0 (SEEK_SET)"
+POS is absolute position. (Seek relative to the start of the file)
+.IP "WHENCE=1 (SEEK_CUR)" 8
+.IX Item "WHENCE=1 (SEEK_CUR)"
+POS is an offset from the current position. (Seek relative to current)
+.IP "WHENCE=2 (SEEK_END)" 8
+.IX Item "WHENCE=2 (SEEK_END)"
+POS is an offset from the end of the file. (Seek relative to end)
+.RE
+.RS 4
+.Sp
+The SEEK_* constants can be imported from the \f(CW\*(C`Fcntl\*(C'\fR module if you
+don't wish to use the numbers \f(CW0\fR \f(CW1\fR or \f(CW2\fR in your code.
+.Sp
+Returns \f(CW1\fR upon success, \f(CW0\fR otherwise.
+.RE
+.ie n .IP "$io\->sysseek( POS, WHENCE )" 4
+.el .IP "\f(CW$io\fR\->sysseek( POS, WHENCE )" 4
+.IX Item "$io->sysseek( POS, WHENCE )"
+Similar to \f(CW$io\fR\->seek, but sets the IO::File's position using the system
+call \fBlseek\fR\|(2) directly, so will confuse most perl IO operators except
+sysread and syswrite (see perlfunc for full details)
+.Sp
+Returns the new position, or \f(CW\*(C`undef\*(C'\fR on failure.  A position
+of zero is returned as the string \f(CW"0 but true"\fR
+.ie n .IP $io\->tell 4
+.el .IP \f(CW$io\fR\->tell 4
+.IX Item "$io->tell"
+Returns the IO::File's current position, or \-1 on error.
