string of contents to replace the file with
a new [entity tag][gfile-etag] for the file, or NULL
TRUE if a backup should be created
a set of GFileCreateFlags
optional gio.Cancellable object, NULL to ignore
a GAsyncReadyCallback to call when the request is satisfied
the data to pass to callback function
Starts an asynchronous replacement of file with the given contents of length bytes. etag will replace the document's current entity tag.
When this operation has completed, callback will be called with user_user data, and the operation can be finalized with g_file_replace_contents_finish().
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.
If make_backup is TRUE, this function will attempt to make a backup of file.
Note that no copy of contents will be made, so it must stay valid until callback is called. See g_file_replace_contents_bytes_async() for a glib.Bytes version that will automatically hold a reference to the contents (without copying) for the duration of the call.
