I've created an example, but no errors is generated, even C code is as
expected. Please help me!
namespace Example {
errordomain InError {
GENERAL
}
public interface In {
[CCode (vfunc_name = "i_fun")]
public abstract void fun (int a, int b) throws Error;
[CCode (vfunc_name = "i_fo")]
public abstract void fo ();
}
class App : Object, In {
public void fun (int a, int b) throws Error {
stdout.printf("a=%i; b=%i\n", a, b);
throw new InError.GENERAL("Fake error");
}
public void fo () {
stdout.printf("Fo....\n");
}
public static int main (string[] args) {
var a = new App();
a.fo();
try {
a.fun(4,5);
}
catch (Error e) {
stdout.printf("Error: %s\n", e.message);
}
return 0;
}
}
}
