What comedilib functions does Labview use?

[Omri Schwarz]

I am trying to put together the following: an NI PCI 6023 card on an Opteron (x86_64 machine) running Linux 2.6.7, and giving its data to Lab View by way of Comedi. I've run into a 64 bit compatibility bug in Comedi that I am fixing, (the COMEDI_DEVCONFIG ioctl) but if I have to make modifications to comedi, knowing that LabView is itself compiled for 32 bit operation, then I have to know what I am doing. So if anyone knows exactly which comedilib function calls LabView uses, I'd be much obliged.

Omri,

You may want to also consider posting this question on the Driver Development Kit (DDK) Discussion Forum (link available below). This forum is monitored by individuals programming National Instruments data acquisition devices without the NI-DAQ driver.

Good luck with your application.

Hi Omri,

I can't help you with the 64-bit stuff but the functions in comedilib are
documented on the comedi site:
http://www.comedi.org/doc/x3563.html#FUNCTIONREFERENCE

There is also the Comedi
Library for Linux on OpenG.org:
http://openg.org/tiki/tiki-index.php?page=Comedi+Library+for+Linux

I looked at your post on the driver-development forum. I hate to redirect
you again but you may find a better audience on the Comedi mailing list:

Hope this helps.
