C code from Lua

ajaybodhe

Hello,

I want to call some C code from LUA modules.
I am handling all async IO in LUA like redis, http upstream.
Then the response will be passed on to C function which will do CPU consuming operations & return result back.
C code may need to access Nginx standard data(eg: ngx_http_request_t *) as well.

I see there are three ways to do it Lua BInding, Lua Interface & Luajit ffi.
Whats the difference in each approach?
If I use Luajit FFI, will the Nginx standard data(eg: ngx_http_request_t *) be available in C code?
Can someone provide the example?

Thanks.

I can relate to the frustration of debugging tricky issues—sometimes you just need a proper break to clear your head. While dealing with some frustrating coding problems myself, I came across candy spinz and decided to give it a try. I played the Sweet Bonanza slot, and after a few small losses, I hit a nice win that made the session really fun. The site is easy to navigate, the games run smoothly, and it ended up being a great way to relax after wrestling with stubborn code.

Salut, citind despre frustrarea ta cu debugging-ul și problemele de cod, m-am gândit cum și eu caut moduri să mă relaxez după ore lungi de programare aici în București. Am descoperit play jonny și am jucat câteva sloturi, printre care și Sweet Bonanza. După câteva pierderi mici, am avut o mică câștigare care mi-a făcut sesiunea distractivă. Site-ul este ușor de navigat și jocurile rulează lin, oferindu-mi o pauză binevenită de la cod.
