Gio.DataInputStream.prototype.read_int64

function read_int64(cancellable: Gio.Cancellable): Number(gint64) {
    // Gjs wrapper for g_data_input_stream_read_int64()
}
  

Reads a 64-bit/8-byte value from stream.

In order to get the correct byte order for this read operation, see Gio.DataInputStream.prototype.get_byte_order and Gio.DataInputStream.prototype.set_byte_order.

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 Gio.IOErrorEnum.cancelled will be returned.
