I want to support standard GTK options in my program but I don't want to use g_option_ processing macros to parse command line.

Now, when I want to print the help of my program (in response to --help option, and using my own code), I need to be able to get a list of the GTK standard options processed by gtk_init.

Unfortunately gtk_get_option_group() returns a GOptionGroup* which however is completely opaque and has no getters!!

This means that there is no way for GTK users which do not use g_option_* parser facilities to get the list of GTK supported options.

A simple 

  gint g_option_group_get_entries(GOptionGroup group, GOptionEntry **p)
  {
      *p = group->entries;
      return group->n_entries;
  }

should do the job.
