C definition of LabView6i "waveform" type

[rich hilt]

I am trying to pass a waveform to a C Library routine to be able to pass
the data to another program. In Labview, the C Library Routine
definition includes a type of waveform, placing a parameter in the call
with the format:

void MyLibRoutine(waveform myWaveform)

The problem I am having is in the library end. Can anyone tell me what
the definition of a type waveform is, or where I can find the
appropriate #include file.

TIA

Rich,

I would recommend parsing the waveform out into its elements (or just the element(s) you need) or change it to a standard cluster, which equates to a structure type in C/C++

Hope this helps

Unforutnately, I'm fairly new to Labview. I have been trying to figure how to do that for the last 2 days. Could you please elaborate on how to do this?

TIA

Rich,

Okay, I did a bit of work. I am not a C/C++ programmer (yet) so I can't guarantee the accuracy of the .c file, but it gives you an idea. Also, keep note of the fact that the CIN is of the wrong data type, but it is a structure.

The .c file contains the structure definition for the "Image" data type, and I also included (in comments) the definition for the waveform type, as accurately as I know of.

The VI contains the conversion of the waveform type into a cluster, as well as the input of the "Image" cluster into the CIN.

I hope this helps
