Device Driver [message #1911]

Hi
I am trying to write a C device driver and link this up to
IDL. I started by using 'call external' but found it a bit slow - the device
driver had to be reinitialised on each call, it seemed that anything
done in previous instances of 'call external' is forgotten when control
returns to IDL. Am I doing something wrong?
Any suggestions on the best way of linking a device driver to IDL would be
gratefully accepted as I am a real novice in this area
Another question I have is: what is the 'export.h' file in the IDL
directory for? In the release notes for version 2.2.2 it is mentioned in the
same breath as'linkimage'.
Thanks in advance
Mark Harmer
