Description

I’m working with an AbortSignal and some C code (extern "C"). I need to pass a reference of AbortSignal.aborted (a boolean) to the C code, which is running in async work.

Right now, I’m using a bool * and addEventListener in C++ with NAPI to update the boolean pointer which is passed to the C code, but this hurts performance. Is there a way to directly reference aborted from C?

Thanks!
