lua调用c++函数,c++调用lua

static int getNum(int num);static int _getNum(lua_State* pL);bool luaDoc::init(){      lua_State*pL=lua_open();      luaopen_base(pL);    lua_register(pL,"_getNum",_getNum);      luaL_difile(pL,"data.lua");      lua_close(pL);      return true;}int  luaDoc::getNum(int num){     return num+1;}int luaDoc::_getNum(lua_State*pL){    int num=(int )lua_tonumber(pL,1);    lua_pushnumber(pL,getNum(num));    return1;}//=========lua文件===========local num=_getNum(10)
