NAME
       ualarm - set the interval timer

SYNOPSIS
DESCRIPTION
       The function causes the signal to be generated for the calling process after the number of real-time microseconds specified by the useconds
       argument has elapsed. When the interval argument is non-zero, repeated timeout notification occurs with a period in microseconds  specified
       by the interval argument. If the notification signal, is not caught or ignored, the calling process is terminated.

       Implementations	may place limitations on the granularity of timer values. For each interval timer, if the requested timer value requires a
       finer granularity than the implementation supports, the actual timer value will be rounded up to the next supported value.

       Interactions between and either or are unspecified.

RETURN VALUE
       The function returns the number of microseconds remaining from the previous call. If no timeouts are pending or if has not previously  been
       called, returns 0.

ERRORS
       No errors are defined.

APPLICATION USAGE
       The function is a simplified interface to and uses the interval timer.
