/* Schedule an alarm. In SECONDS seconds, the process will get a SIGALRM.

If SECONDS is zero, any currently scheduled alarm will be cancelled.

The function returns the number of seconds remaining until the last
|

alarm scheduled would have signaled, or zero if there wasn't one.

There is no return value to indicate an error, but you can set `errno'

to 0 and check its value after calling `alarm', and this might tell you.

The signal may come late due to processor scheduling. */
