Normally I used this method of coding:

int main (int argc, char **argv)
{
  struct AppData appData; // personal structure
  GtkApplication *app;
  gint status;

  app = gtk_application_new (PROGRAM_ID, G_APPLICATION_DEFAULT_FLAGS);  
  g_signal_connect (app, "startup", G_CALLBACK (cb_startup), &appData);
  g_signal_connect (app, "activate", G_CALLBACK (cb_activate), &appData);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}

I’m trying to adapt my code like the trivial example:

include <gtk/gtk.h>

#include "exampleapp.h"

int main (int argc, char *argv[])
{
  struct AppData appData; // personal structure
  return g_application_run (G_APPLICATION (example_app_new ()), argc, argv);
}

My question is: how can I pass my personal structure in the above style code?
