示例1:
/**
* ev_document_load:
* @document: a #EvDocument
* @uri: the document's URI
* @error: a #GError location to store an error, or %NULL
*
* Loads @document from @uri.
*
* On failure, %FALSE is returned and @error is filled in.
* If the document is encrypted, EV_DEFINE_ERROR_ENCRYPTED is returned.
* If the backend cannot load the specific document, EV_DOCUMENT_ERROR_INVALID
* is returned. Other errors are possible too, depending on the backend
* used to load the document and the URI, e.g. #GIOError, #GFileError, and
* #GConvertError.
*
* Returns: %TRUE on success, or %FALSE on failure.
