Returns a list of registered sources, sorted by display name.
If extension_name is given, restrict the list to sources having that extension name.
The sources returned in the list are referenced for thread-safety. They must each be unreferenced with unref when finished with them. Free the returned list itself with g_list_free.
An easy way to free the list properly in one step is as follows:
g_list_free_full (list, g_object_unref);| this | |
| extension_name |
an extension name, or |

a sorted list of sources |
