Issue Description:

251 let fd = Int(bitPattern & 0x00000000FFFFFFFF)

252 let poll_mask = Int(bitPattern >> 32) // shift out the fd

253 print("io_uring_peek_batch_cqe bitPattern[" + String(bitPattern).decimalToHexa + "] bit[(bitPattern)] fd[(fd)] i[(i)] poll_mask[(poll_mask)] currentCqeCount[(currentCqeCount)] cqes[Intℹ][(String(describing:cqes[Intℹ]))]")
