gFileEnumeratorNextFilesAsync {RGtk2} | R Documentation

## gFileEnumeratorNextFilesAsync

### Description

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.

### Usage

    gFileEnumeratorNextFilesAsync(object, num.files, io.priority = 0,
        cancellable = NULL, callback, user.data = NULL)

### Arguments

``object`` | a `GFileEnumerator`.
``num.files`` | the number of file info objects to request
``io.priority`` | the io priority of the request.
``cancellable`` | optional `GCancellable` object, `NULL` to ignore.
``callback`` | a `GAsyncReadyCallback` to call when the request is satisfied
``user.data`` | the data to pass to callback function

### Details

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`.
