Named pipes Windows (OpenG implementation)

$

Greetings,

 

I've run into a few issues with the OpenG Named Pipes implementation (by rolfk). I am unsure how much of this is due to my inexperience with pipes and how much is caused by the aging OpenG (beta) implementation.

 

Usage:
I want to pick up existing named pipes with LabVIEW to read data from them. Basic test case (simple example .vi from OpenG library) works (attached screenie 1).

 

Problem:
If I try to pick up pipe opened in separate .vi (or external to LabVIEW by third party software) I get error 42 when attempting to read it (screenie 2)

 

Questions:
Is there a resource to determine what the error codes cover? (I've also seen error 8, screenie 3, but only found description for error 6)
Is there reason to believe that the named pipe implementation no longer functions in Win7/LV8?

Am I butchering proper named pipe procedure and use?

 

Thank you in advance for your consideration!

 

Nicolai
