Binding stateful functions as function pointers

by Mark Boyall

Excerpt:

This proposal is motivated by the lack of a means to pass stateful functions to C APIs as a function pointer. Solving this problem would benefit everybody who has to call into a C API. The approach outlined here of a thunk, or trampoline, is well-understood and used commonly in language implementations which include a JIT compiler.
