pointers in IDL and C

[Ramji Digumarthi <ramji.digumarthi(at)lmco.com>]

Hi folks,

I have simple question:
I create a Heap variable of int array called Im_arr, and create 
a pointer to the heap variable Im_arr. Now I spawn a C-code that will
read an image from a camera. I pipe the pointer to Im_arr, to the
spawned process. 

Here is question : Can use the pointer value from IDL as pointer in
C-code to write image data directly to the heap variable Im_arr???

any suggestions that I can do above operation or some thing like that???

thanks in advance????
