How do I lookup the full name of a registered enum type in glib?

Question

I have a number of enumerations that were created via the standard glib registration function:

GType foo_type = g_enum_register_static("Foo", foo_enum_values);

But when I try to recover the name ("Foo") that I registered the enumeration with, I get its basic class instead:

gchar const * type_name = g_type_get_name(foo_type);
printf("%s\n",type_name);

prints "GEnum" and not "Foo". How can I get back the string "Foo" given just the registered type id?

I can’t check your code fully because you haven’t provided a minimal working reproducer, but the following code works fine for me:

/* gcc -o test test.c $(pkg-config --cflags --libs glib-2.0 gobject-2.0) */
#include <glib.h>
#include <glib-object.h>

static const GEnumValue my_enum_values[] =
{
  { 1, "the first value", "one" },
  { 2, "the second value", "two" },
  { 3, "the third value", "three" },
  { 0, NULL, NULL }
};

int
main (void)
{
  GType type;

  type = g_enum_register_static ("MyEnum", my_enum_values);

  g_assert_cmpstr (g_type_name (type), ==, "MyEnum");

  return 0;
}
