Using the C language to extend the Lua language feature __c language

Lua is an important part of Openresty (Nginx+lua), and when native Lua doesn't meet the requirements, it needs to be extended with Lua in C, like I wrote my own time module below.

#include <stdio.h>
#include <stdlib.h>
#include <sys/timeb.h>
#include <lua_ openresty/lua.h>
#include <lua_openresty/lauxlib.h>
#include <lua_openresty/lualib.h>

static int l_yourownname (lua_state *l)
{
	... Here write your own code
}


static const struct LUAL_REG yourownname2[] = {
	{"Yourownname", L_yourownname},
	{NULL, NULL}
};


extern int Luaopen_yourownname3 (lua_state* L)
{
	lual_newlib (l,yourownname2); return 1;
}

Compile this file into a a.so file for a dynamic-link library, and finally use it in LUA

Local A = require "a";
Local des = Libencode.yourownname ();
Print (DES)
