the number of file info objects to request
the io priority of the request.
optional GCancellable object, NULL to ignore. [allow-none]
a GAsyncReadyCallback to call when the request is satisfied. [scope async]
the data to pass to callback function. closure
Request information for a number of files from the enumerator asynchronously. When all i/o for the operation is finished the callback will be called with the requested information. The callback can be called with less than num_files files in case of error or at the end of the enumerator. In case of a partial error the callback will be called with any succeeding items and no error, and on the next request the error will be reported. If a request is cancelled the callback will be called with G_IO_ERROR_CANCELLED. During an async request no other sync and async calls are allowed, and will result in G_IO_ERROR_PENDING errors. Any outstanding i/o request with higher priority (lower numerical value) will be executed before an outstanding request with lower priority. Default priority is G_PRIORITY_DEFAULT.
