It's actually pretty convenient.  If you pass TRUE in to g_string_free() it
frees the GString struct and the character data.  If you pass in FALSE it only
frees the GString struct and returns the character data.  Here's an example:

static gchar *create_hello_message() {
  GString *str = g_string_new("");

  g_string_append(str, "Hello");
  g_string_append(str, ", world!");

  return g_string_free(str, FALSE);
}
