[LLVMdev] Running functions built with the LLVM C API

The Kaleidoscope tutorial shows how to get a void pointer to the a built function, cast it to the appropriate type, and then call it.
There isn’t a tutorial using the LLVM C API that I’ve seen, so I’ve been working with bits and pieces found online, and of course the header files. I haven’t been able to find an equivalent to getPointerToFunction as yet, however. The JIT example I found is using LLVMRunFunction, with requisite boxing of arguments and unboxing of return value.
Is this the recommended route? Is the C API just lacking a getPointerToFunction equivalent? If so, I imagine it will be fairly straightforward to add one, which I’ll be happy to do.
Thanks very much,
