DataInputStream.readUptoAsync

The asynchronous version of gio.data_input_stream.DataInputStream.readUpto. It is an error to have two outstanding calls to this function.

In contrast to gio.data_input_stream.DataInputStream.readUntil, this function does not consume the stop character. You have to use gio.data_input_stream.DataInputStream.readByteData to get it before calling gio.data_input_stream.DataInputStream.readUpto again.

Note that stop_chars may contain '\0' if stop_chars_len is specified.

When the operation is finished, callback will be called. You can then call gio.data_input_stream.DataInputStream.readUptoFinish to get the result of the operation.
