A function call instead of doing the > atomic_long_inc() in Rust? Yeah, I complained about something similar a while ago. And recently talked to Boqun about this as well, Bindgen *could* in theory 'compile' the inline C headers into (unsafe) Rust, the immediate problem is that Rust has a wildly different inline asm syntax (because Rust needs terrible syntax or whatever). Boqun said it should all be fixable, but is a non-trivial amount of work.
