Array to Variant

[Bertrand_ENAC]

Hello,

Below you will see to examples of code

{
 VARIANT XV,
 double x[2][4];
 
 CA_VariantSet2DArray (&XV, CAVT_DOUBLE, 2, 4, x);  
 
}

{
 VARIANT XV,
 double *x[2];
 
 x[0] = malloc (4 * sizeof (double));
 x[1] = malloc (4 * sizeof (double)); 
 CA_VariantSet2DArray (&XV, CAVT_DOUBLE, 2, 4, x);  
 
}

The first one is working the second not. Why?

How can I used varable array sizes with VARIANTS?

Thank you

Bertrand

I have had the same problem some time ago ang got an answer that I couldn't find at the moment: basically, the reason is that the system does not guarantees that dynamically created arrays like yours are contiguous, so the translation to VARIANT cannot be completed. With static arrays like your first example this is always guaranted. I will try to locate the discussion to link it for you.

Roberto, was this the link you had in mind?

Yes, JR, thanks for adding the link!

I was so involved in that problem that I thought to have posted this question personally! Thats why I couldn't find it in my recent posts: getting old too rapidly?
