Named pipe stream classes  V1.0

The named pipe stream classes were written using Watcom 10a, under OS/2.
This was my first attempt at writing new classes derived from streambuf,
and istream/ostream, so there may be problems.

Files:
	in.cpp        opens a named pipe and sends the data to stdout
	out.cpp       creates a named pipe and sends stdin to the pipe

	pipestrm.h    named pipe header
	pipestrm.cpp  named pipe source


Classes:
	Pipebuf
	iNPstream
	oNPstream
	(sorry no ioNPstream)

The Pipebuf class uses three member functions to read/write to a
named pipe: underflow, overflow and sync.

Currently, the class can only be used for input or output but not
both.  The most likely way to have an i/o Pipe would be to split
in half and use one half for the get area, and the other half for
the put area.


oNPstream::oNPstream()  creates an output named pipe stream object,
	does not create a pipe.
	
oNPstream::oNPstream(const char*)  creates an output named pipe stream
	object and creates and connects to the pipe.  The string
	doesn't need the \pipe\ prepended, the class automatically
	does that for you.
	
oNPstream::open(const char*)  creates and connects to a named pipe.
	if a pipe is already, it returns 0.

oNPstream::close()  closes a named pipe.  Returns 0 if there is no
	pipe open.
	
The iNPstream function members are essentially the same except that
	iNPstream::open(const char*) opens the pipe and doesn't create
	a pipe.
