.SH SYNOPSIS
.ft B
.ta1i 2i
.nf
#include <iostream.h>
#include <pipestream.h>

.SH DESCRIPTION
\f(CWpipestream\fR 
specializes
\f(CWiostream\fR
to use a circular buffer (\f(CWpipebuf\fR).
.PP
Assume
.br
\(em \fBps\fR is a \f(CWpipestream\fR.
.br
\(em \fBptr\fR is a \f(CWchar*\fR.
.br
\(em \fBlen\fR is an \f(CWint\fR.
.br
\(em \fBpb\fR is a \f(CWpipebuf*\fR.
.PP
Constructors:
.TP
\fBpipestream()\fR
Constructs a \f(CWpipestream\fP with an empty \f(CWpipebuf\fR.
.TP
\fBpipestream(ptr,len)\fR
Constructs a \f(CWpipestream\fP with a \f(CWpipebuf\fR
that uses the \fBlen\fR bytes
at \fBptr\fR as a reserve area.
.PP
Members:
.TP
\fBpb=ps.rdbuf()\fR
Returns the associated \fBpipebuf\fR. \fBpipebuf::rdbuf\fR has
the same semantics as \fBstreambuf::rdbuf\fR, but the type of
the result is more precise.
