XIA API receives null pointer for pxisys.ini #73

Closed spaulaus closed 4 years ago

spaulaus commented 6 years ago

Expected Behavior

The API should be able to load pxisys.ini as specified in the configuration file.

Current Behavior

Error when loading pxisys.ini

For some reason we're passing in null for the pxisys file name. It's set properly according to the cout statements but it's not getting to the API for some reason.

Context

Error only presents itself when trying to communicate with actual hardware through the API. From what I can tell the API sees this as a null pointer. Memory inspection shows this pointer as not null, and set to the proper value just before executing the API call.

Possible Solution (optional)

Acceptance Criteria

This seems to be an issue with the XIA API. I'm closing this as we won't fix it. I think XIA is working on a fix though.
