What's the difference, when you say C function vs. Lua C API function?
C function:
int foo(int bar) { return bar * 3; }
Lua C API function:
int luafoo(lua_State *L) { int bar = luaL_checkint(L, 1); lua_pushnumber(L,
foo(bar)); return 1; }
You can call C functions directly from inside LuaJIT by using its FFI. More
