load_partial_contents_async

Description:

public async bool load_partial_contents_async (Cancellable? cancellable = null, FileReadMoreCallback read_more_callback, out uint8[] contents, out string etag_out) throws Error

Reads the partial contents of a file.

A FileReadMoreCallback should be used to stop reading from the file when appropriate, else this function will behave exactly as load_contents_async. This operation can be finished by load_partial_contents_async.end.

Users of this function should be aware that user_data is passed to both the read_more_callback and the callback.

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error g_io_error_cancelled will be returned.

Parameters:

this	input File
cancellable	optional Cancellable object, null to ignore
read_more_callback	a FileReadMoreCallback to receive partial data and to specify whether further data should be read
callback	a TaskReadyCallback to call when the request is satisfied
user_data	the data to pass to the callback functions
