I have a program that I've been developing that has been successfully using
named pipes for interprocess communications on OS/2 2.1.  Now on OS/2
3.0,sometimes the named pipe communication fails in a way that seems to
indicate that their might be some kind of buffer size problem.  So I went
to go look in the documentation for DosCreateNPipe() to verify that I was
passing the write parameters. But there is a problem -- the documentation
does not agree on the order of the parameters!

The OS/2 3.0 toolkit lists the input buffer size before the output buffer
size.  But the example code does the opposite.

The OS/2 2.1 toolkit lists the output buffer size before the input buffer
size.  The example code agrees with this.

I was making calls according to the parameter order of the OS/2 2.1
toolkit. On OS/2 2.0, 2.1, and 2.11 it worked fine.  But now it doesn't
always work properly.

Did IBM change the parameters for DosCreateNPipe()?  Which is the correct
order for the parameters in OS/2 3.0?
