Re: [Vala] trying vapi file for ngspice, segfaults

[Andre Masella <andre masella name>]

The test method can't have a type argument:

        public static int test(string stdout,int id, int data){
                stdout.printf ("stdout: '%d'\n", data); //debug line
                return id;
        }
