Is it possible to store lua function in a C struct?

Hi all,

Is it possible to store lua function in a C struct and later call lua function from C using the stored information?

I am looking for an implementation as following:

void* myluafunc = luaL_checkluafunction (L, 1);

lua_pushfunctionptr (L, myluafunc);

lua_call (L,0,0);

I have implemented a workaround where lua function's name is stored in a char array in C and then later on lua function is called using following APIs. This way is working fine but using function name as the identifier is using extra memory.

char name[128];

int button_lua_new (lua_State *L)

{

const char* myluafuncname = luaL_checkstring (L,1);

strcpy (name, myluafuncname);

}

void call_button_event_handler ()

{

lua_getglobal(L, name);

lua_call (L,0,0);

}

Thanks
