Q:how to allocate memory in CINs?

[gxchem@my-deja.com]

Hi, Labview fellas,

I am using CINs(code interface Node) to process some array stuffs. I
know the CIN function setCINArraySize() is good for allocating memory
for an output array. But how can I declare an array for CIN's local use?
I tried to use:

float32 *array=(float32 *array)malloc(numElmts);

and, also, I tried to use:

TdHdl **array;
NumericArrayResize(int32 fS, 1, (UHandle *)array, nx);

Unfortunately, both of them caused illegal operations.

Please help me!!


Thanks.

There is a header file included in your CIN. It exports some
functions like DSNewPtr, DSNewHandle, DSDisposeHandle, and
DSDisposePtr.

I'm a little surprised that a call to malloc crashed, but I
haven't tried it in a very long time; so it might be necessary
to use one of the ones listed above.

I forgot to multiple numElmts by float32:>)

it works now. Thanks!
