14 io_tryreadtimeout is identical to io_tryread, with the following excep‐
15 tion: if
16
17
18 · io_tryread returns -1 (the descriptor is not ready for reading), and
19
20 · the descriptor has a timeout, and
21
22 · the read attempt was after the descriptor's timeout,
23
24 then io_tryreadtimeout instead returns -2, with errno set to ETIMEDOUT.
