I suspect that the function is calling external code via something like
CALL_EXTERNAL or LINKIMAGE. I've gotten error messages like that in the past
when mixing IDL with external code.

The descriptor is the thing which describes a variable in IDL. It contains the
datatype, array dimensions, and the physical location of the data in memory.
When you pass around variables in IDL, you're really passing around the
descriptors.
