Hi TheGame,

You can use the Call Library Node function from within LV.  Simply make sure that the CVI code function returns a value (example: int functioname (typedef value1, etc) ).

You can send the values to the function and it returns a value linked to an error code.  For instance, 0 = no-error, -1 = bad error, etc.  You can also return messages, such as +1 = function completed, etc.. 

Ooops, I'm getting carried away 😄

The Context Help provide adequate information on how to wire the Call Library Node.  You can do a search on the function as well.
