DESCRIPTION

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.
