[LLVMdev] Opaque type usage to represent foreign types

[Robert Zeh]

In my project I have a group of foreign types (C++ classes) that I  
want to use, but don't want to represent as structs within LLVM.  For  
example, for each field in each C++ class I have a setter and getter  
function that I'd like to use.  The setters and getters are "extern C"  
functions to avoid problems with C++'s name mangling.

After going over the documentation it seems like I can do this by  
creating a unique opaque type for each C++ class to track types during  
my compilation, and then resolving all of the opaque types to void*

Is this a reasonable approach?
