Talking with my C data [message #13437]

Howdy,

This group has helped so much in the past I hope you all can help me
prove to my bosses, once again, that IDL will do most anything.

I am collecting images with a CCD using C code I wrote with some
supplied C libraries we purchased with the camera. Right now once the
data is readout from the camera it is stored in a data stream in memory
and is then put into a file using fwrite. I have a couple of questions:

I would like to write IDL code to manage the taking and displaying of
the data. Should I use call_external or linkimage? Is there a speed
difference or just a level of complexity difference?

Once the data is read out of the camera into memory can I use IDL to
read the data from the memory or should I continue to have C write the
data with fwrite and then can I have IDL read that data from the file
created with fwrite? In either case I am not sure how to make IDL get
the data.

I've got to believe this is done frequently and I will continue to look
through the RSI documentation and David Fanning's great book, but at
this point I haven't figured it all out.

Thanks for any help.

Eric
