The idea is to pass a structure with these two arguments

when you have a function

void function(type1 * arg1, type2 * arg2)
{
 ....
}


you have to define a second function and a structure :

struct struct_arg1_arg2
{
   type1 * arg1;
   type2 * arg2;
};

void function_prime(struct struct_arg1_arg2 * arg)
{
   function(arg->arg1, arg->arg2);
}

to call the function, you do the following :

{
   struct struct_arg1_arg2 data;
   data->arg1 = arg1;
   data->arg2 = arg2;
   gtk_timeout_add(interval, function, &data);
}
