Direct Memory Access [message #9535]

I have a hypothetical question. Consider a large block of memory which
contains a series of images (say 8-bit deep pixels) put there by, for
instance, a digital camera. Does there exist the possibility of
accessing that memory directly in IDL, given that you know the fixed
memory address at which the image will be stored (or, if not a fixed
address, can at least be given it)? A pointer in C accomplishes this
nicely, but I don't know of an equivalent, low-level, hook in IDL. No
doubt some of you have implemented real-time data acquisition into IDL
and have dealt with this problem. Thanks for your help.
