TrueTime Card and how to interface with dll file!?

[tk003k]

I am trying to interface with a PCI-SG 2U (IRIG) timing card (Used to made by TrueTime, now Symmetricom).  Does anyone have a solution for this card in LV 2009?  

If not, can anyone give advice on writing code to interface with .dll file?  I am not sure how to pass through the "GENERIC_READ | GENERIC_WRITE" into the function to open the device. The function says to open it is: 

TT_OpenDevice(boardID, GENERIC_READ | GENERIC_WRITE, &hDevice)

No clue on how to pass this in.  Can anyone help?

Thanks -

Hi Tom,

do you have a header file for you dll? If yes, then the values for Generic_Read and Generic_Write should be defined there.

Edit: as you can see here, you should have also the source code if you have the SDK. From there you can read the defined values for what you need.

Thanks Mike.  I do have the .h file and the sdk information.  I went through and used the Import>Shared Library Tool and was able to find all the header information that way.  I guess that my problem/question is, the documentation says that it is a DWORD to pass as an input, but LabVIEW says it is a uint32.  I guess the real question is, what the heck do I pass in to the dll function?  Should it be the string "GENERIC_READ | GENERIC_WRITE" or something else?

Thanks -

Hi Tom,

it is a number. Connect it as a UINT32. The needed value should be part of the header file.
