68  * Description
69  * Provides a base class for implementing asynchronous function results.
70  * Asynchronous operations are broken up into two separate operations
71  * which are chained together by a GAsyncReadyCallback. To begin
72  * an asynchronous operation, provide a GAsyncReadyCallback to the
73  * asynchronous function. This callback will be triggered when the
74  * operation has completed, and will be passed a GAsyncResult instance
75  * filled with the details of the operation's success or failure, the
76  * object the asynchronous function was started for and any error codes
77  * returned. The asynchronous callback function is then expected to call
78  * the corresponding "_finish()" function, passing the object the
79  * function was called for, the GAsyncResult instance, and (optionally)
80  * an error to grab any error conditions that may have occurred.
81  * The "_finish()" function for an operation takes the generic result
82  * (of type GAsyncResult) and returns the specific result that the
83  * operation in question yields (e.g. a GFileEnumerator for a
84  * "enumerate children" operation). If the result or error status of the
85  * operation is not needed, there is no need to call the "_finish()"
86  * function; GIO will take care of cleaning up the result and error
87  * information after the GAsyncReadyCallback returns. Applications may
88  * also take a reference to the GAsyncResult and call "_finish()"
89  * later; however, the "_finish()" function may be called at most once.
90  * Example of a typical asynchronous operation flow:
91  * $(DDOC_COMMENT example)
92  * The callback for an asynchronous operation is called only once, and is
93  * always called, even in the case of a cancelled operation. On cancellation
94  * the result is a G_IO_ERROR_CANCELLED error.
95  * Some asynchronous operations are implemented using synchronous calls.
96  * These are run in a separate thread, if GThread has been initialized, but
97  * otherwise they are sent to the Main Event Loop and processed in an idle
98  * function. So, if you truly need asynchronous operations, make sure to
99  * initialize GThread.
