io_timeout(3)         DragonFly Library Functions Manual         io_timeout(3)

NAME
       io_timeout - set time limit on descriptor

SYNTAX
       #include <io.h>

       void io_timeout(int64 fd,tai6464 deadline);

DESCRIPTION
       The io library keeps track of an optional ``timeout'' for each
       descriptor. The timeout is a specific moment in time, stored in a
       tai6464 variable.

       io_timeout(d,t) sets the timeout for descriptor d to t.

       io_timeout has no return value; it always succeeds. (Space to store the
       timeout was already allocated as part of the descriptor.) It has no
       effect if d is not the number of a descriptor.

       Note that you have to call io_timeouted to be notified of timeouts,
       just like you are calling io_canread or io_canwrite for read and write
       notification.
