You can do it this way, but you can do it a way more
resembling your original description too. I don't know what
your intended error reporting interface for other I/O errors
looks like, but if it can be querried after the fact, i.e.
it maintains something like errno, then
buf = g_object_new(X_TYPE_FILE_BUFFER, "filename", "foo.txt", NULL);
if (!buf) {
...
}
can be done completely equivalently
buf = g_object_new(X_TYPE_FILE_BUFFER, "filename", "foo.txt", NULL);
if (x_file_buffer_error(buf)) {
...
g_object_unref(buf);
}
If not, the x_file_buffer_load_from_file() approach with
immediate error reporting makes more sense.
