Passing > 64Kb arrays to IDL DLL's [message #4088]

Hi,

I use IDL v 3.6.1a on a PC. I would like to find out if one can
pass arrays larger than 64Kbytes to DLL functions using
CALL_EXTERNAL. I have been trying to pass long arrays of
size > 16384 elements, which means greater than 64K bytes;
so far I haven't been successful. FYI I have used huge
pointers to access the array elements.

I know I can do my operations within IDL itself, but I may
speed up my total execution time, if I perform some of the
processing in C. Most of it involves FOR loops over images.
If anybody has experience with writing DLL's for IDL,
please advise me.

Thanks

Sandeep Dalal
