Are there size limits in DAQmxGetDevDOLines

[APO67]

Hi all,

I'm using the text based DAQmx interface (Version 9.1.0) and try to find the names of all digital output terminals with the following code snippet:

 char data[1024];

DAQmxGetDevDOLines("Dev1", data, 1024);

and get always an incomplete string cutted at position 430 like this:

"Dev1/port0/line0, Dev1/port0/line1, Dev1/port0/line2, Dev1/port0/line3, Dev1/port0/line4, Dev1/port0/line5, Dev1/port0/line6, Dev1/port0/line7, Dev1/port1/line0, Dev1/port1/line1, Dev1/port1/line2, Dev1/port1/line3, Dev1/port1/line4, Dev1/port1/line5, Dev1/port1/line6, Dev1/port1/line7, Dev1/port2/line0, Dev1/port2/line1, Dev1/port2/line2, Dev1/port2/line3, Dev1/port2/line4, Dev1/port"

Are there any size limitations? Work arounds?

Thanks

Hello,

unfortunately I’m not able to reproduce the problem you’re describing.
I tested the “DAQmxGetDevDOLines" function with a NI PCI 6289 board and get the following result:

6289/port0/line0, 6289/port0/line1, 6289/port0/line2, 6289/port0/line3, 6289/port0/line4, 6289/port0/line5, 6289/port0/line6, 6289/port0/line7, 6289/port0/line8, 6289/port0/line9, 6289/port0/line10, 6289/port0/line11, 6289/port0/line12, 6289/port0/line13, 6289/port0/line14, 6289/port0/line15, 6289/port0/line16, 6289/port0/line17, 6289/port0/line18, 6289/port0/line19, 6289/port0/line20, 6289/port0/line21, 6289/port0/line22, 6289/port0/line23, 6289/port0/line24, 6289/port0/line25, 6289/port0/line26, 6289/port0/line27, 6289/port0/line28, 6289/port0/line29, 6289/port0/line30, 6289/port0/line31, 6289/port1/line0, 6289/port1/line1, 6289/port1/line2, 6289/port1/line3, 6289/port1/line4, 6289/port1/line5, 6289/port1/line6, 6289/port1/line7, 6289/port2/line0, 6289/port2/line1, 6289/port2/line2, 6289/port2/line3, 6289/port2/line4, 6289/port2/line5, 6289/port2/line6, 6289/port2/line7

These are 883 characters.

Which board are you using?
Have you tried it with another board?
Have you tried it with a simulated board?

Hi Ulrich,

today I tried to reproduce my problem. But it works perfectly. It could be a problem with my debugger string display because the 430 seems to be correct for the string length. (USB-6251 simulated board)

Thanks
