String data passed to DDC_SetDataValues

[hrodstein]

Using the DIAdem connectivity library, you can call DDC_SetDataValues to store data in a channel. If the channel contains string data, what is the format for the values parameter? My guess would be a sequence of back-to-back null-terminated strings but the API documentation does not say.

Hi hrodstein,

Are you using NI's software CVI, or are you using a MicroSoft C compiler?

I'm using MS Visual C++ 2005 with the DIAdem Connectivity Library DLL API.

I figured this out. When storing string data, DDC_SetDataValues takes a pointer to an array of pointers to C strings, like DDC_GetDataValues.

This is documented for  DDC_GetDataValues. It should also be documented for DDC_SetDataValues.
