Exception thrown by DataRight IQ Library

Question

I am attempting to use the library that ships with DataRight IQ to integrate this into our processes.
Specifically, the library is drllib.dll and the function that I am having an issue with is drl_item_get_text.
The error it returns is this: NULL output buffer passed to GetItem.
I have verified that the string I am passing in as the buffer works for other items that expect the same arguement (a char array) and am able to use it to return various things (such as the version).
I have checked numerous times that I am using the same signature as in the documentation (passing the same arguements that are expected) and have run out of ideas with what I am doing wrong.
I would appreciate any help with this very much.
Kind regards,
Ernest

Thanks for your reply!
I'm still a little conufsed though ...
Does that mean that PDEColorSpaceGetStruct function doesn't work for those color spaces at all? Or only in certain conditions?
The on-line reference says that it supports all color spaces except Pattern. And the PDEColorSpaceStruct seems to support them as well (looking at its members).
