int schd(time_t,fptr_t); /* Call a function at a specific time */int aftr(time_t,fptr_t); /* Call a function after spec delay */
- It's the difference between specific time '3 PM tomorrow' and specific delay 'an hour from now'.One is absolute and the other is relative.
So schd() is just a function used by aftr()? So I should only care about aftr()?
