c 使用lua 示例

#include <stdio.h>
#include <string.h>
#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

static int say_hello(lua_State *L)
{
	const char *s = lua_tostring(L,1);
	printf("hell,%s\n",s);
	return 0;
}

int main(void)
{
	lua_State *L = luaL_newstate();;
	luaL_openlibs(L);
	
	//写入全局变量

	lua_pushnumber( L, 211 );
	lua_setglobal( L, "hp" );

	//lua_pop(L,2);

	//读取全局变量
	lua_getglobal( L, "hp" );   
	int res = lua_tointeger(L, -1);
        printf("%d\n",res);

	lua_pop(L,1);

	//设置一个有名称的table
	lua_newtable(L);

	lua_pushinteger(L, 10025);
	lua_setfield(L, 1, "id");

	lua_pushinteger(L, 3);
	lua_setfield(L, 1, "good_count");

	lua_setfield(L, 1, "outlet_count");

	lua_setglobal(L,"customer_table");
		
	//读取table中的值
	int result;

	lua_close(L);	
	return 0;
