I am creating a named pipe in a full screen OS/2 session.  In a DOS
session, I'm fopen'ing the named pipe and fread'ing from it.

The writing (OS/2) process writes 100 strings to the pipe in a fast
loop.  The reading (DOS) process reads from the pipe, also in a
fast loop.  I have specified the NP_WAIT flag when creating the
pipe.

My problem is this: after reading some strings from the pipe
correctly, the fread() of the DOS process returns 0, indicating that
it failed to read anything from the pipe.

Why is this?  Is the DOS process reading faster than the OS/2
process is writing?  I would like the fread() to be blocking,
and that's why I used NP_WAIT.  Does this parameter work only
in OS/2 sessions?

What is the best way to deal with this situation?  Do I have to loop
until the fread returns something?  Is there any kind of DosSleep()
I can use in a DOS session?

Thanks for any help.
