Cannot Find Documentation for DAQmxSetTrigAttribute

[Martin Dale]

Dear all,

The example program that comes with NIDAQmx (DigPulseTrain-Cont-PauseTrig) uses a function called DAQmxSetTrigAttribute but I cannot find any documentation on the use of this function or any of the others in the same block within the NIDAQmx.h header file:

The example program contains the following lines:

DAQmxErrChk (DAQmxSetTrigAttribute(*taskHandle,DAQmx_PauseTrig_Type,DAQmx_Val_DigLvl));
DAQmxErrChk (DAQmxSetTrigAttribute(*taskHandle,DAQmx_DigLvl_PauseTrig_Src,triggerSource));
DAQmxErrChk (DAQmxSetTrigAttribute (*taskHandle, DAQmx_DigLvl_PauseTrig_When,pauseWhen));

And the NIDAQmx.h header file contains these function definitions:
int32 DllExport __CFUNC_C DAQmxGetTrigAttribute (TaskHandle taskHandle, int32 attribute, void *value, ...);
int32 DllExport __CFUNC_C DAQmxSetTrigAttribute (TaskHandle taskHandle, int32 attribute, ...);
int32 DllExport __CFUNC DAQmxResetTrigAttribute (TaskHandle taskHandle, int32 attribute);


Does anybody know what the different parameters are and how to use these functions?

Regards

The attribute ids that are valid for the DAQmxSetTriggAttribute() are in the NIDAQmx.h file can be found under the heading

"//********** Trigger Attributes **********"

These include attributes for start, reference, pause, and arm start triggers.

I hope this helps!
