# sleep(3)

    NAME
         sleep - suspend execution for interval

    SYNOPSIS
         #include <unistd.h>

         unsigned int sleep(unsigned int seconds)

    DESCRIPTION
         The current process is suspended from execution for the number of seconds
         specified by the argument.

         The routine is implemented by setting an alarm timer and pausing until it
         occurs.   The previous state of this timer is saved and restored.  If the
         sleep time exceeds the time to the expiration of the previous timer,  the
         process  sleeps only until the signal would have occurred, and the signal
         is sent 1 second later.
