error: expected expression before ‘int’ while compiling

[Poseidon]

Hi guys,

Ive been trying to add this to the end of script.c at line 23440

	int viewpointmap_sub(struct block_list *bl, va_list ap) {
	struct map_session_data *sd;
	int npc_id, type, x, y, id, color;
	npc_id = va_arg(ap, int);
	type = va_arg(ap, int);
	x = va_arg(ap, int);
	y = va_arg(ap, int);
	id = va_arg(ap, int);
	color = va_arg(ap, int);
	sd = (struct map_session_data *)bl;
	clif_viewpoint(sd, npc_id, type, x, y, id, color);

	return 0;

}

BUILDIN_FUNC(viewpointmap) {
	int type, x, y, id, color, m;
	const char *map_name;
	map_name = script_getstr(st, 2);

	if ((m = map_mapname2mapid(map_name)) < 0)
		return true; // Invalid Map

	type = script_getnum(st, 3);
	x = script_getnum(st, 4);
	y = script_getnum(st, 5);
	id = script_getnum(st, 6);
	color = script_getnum(st, 7);
	map_foreachinmap(viewpointmap_sub, m, BL_PC, st->oid, type, x, y, id, color);
	return true;
}


// Add this to the list of script commands defined, look through the code, should be self explanitory.
	BUILDIN_DEF(viewpointmap,"siiiii"),

but i receive this error

script.c:23441:2: error: expected expression before ‘int’
  int viewpointmap_sub(struct block_list *bl, va_list ap) {
  ^
Makefile:76: recipe for target 'obj/script.o' failed
make[1]: *** [obj/script.o] Error 1
make[1]: Leaving directory '/home/rob/rathena/src/map'
Makefile:51: recipe for target 'map' failed
make: *** [map] Error 2

the file i got the code from ask me to add the code anywhere in between BUILDING_FUNC's i believe i have done that but obviously i haven't as it is giving errors out while compiling on Ubuntu server

Any help will be appreciated

Kind regards
