using log interface from shared library

martin.gee

I have a shared library I'm loading using ffi.load

I'd like use the error log from the shared lib. Digging through the NGINX / Openresty code I see that a request has a pointer to the logger.

Can openresty pass the request object or logger handle to a shared library function?

Not directly since NGINX does not have an ABI. You can write a minimal
nginx C module to expose a proper ABI for your shared library (you can
use Lua FFI to glue them together if desired).
