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.
