UALARM(3)							     UALARM(3)

NAME
       ualarm - schedule signal after specified time

SYNOPSIS
       unsigned ualarm(value, interval)
       unsigned value;
       unsigned interval;

DESCRIPTION
       This is a simplified interface to setitimer(2).

       Ualarm  causes  signal  SIGALRM,	 see  signal(3C),  to  be  sent to the
       invoking process in  a  number  of  microseconds	 given	by  the	 value
       argument.  Unless caught or ignored, the signal terminates the process.

       If  the	interval argument is non-zero, the SIGALRM signal will be sent
       to the process every interval  microseconds  after  the	timer  expires
       (e.g. after value microseconds have passed).

       Because	of  scheduling	delays,	 resumption  of	 execution of when the
       signal is caught may be delayed an arbitrary amount.

       The return value is the amount of  time	previously  remaining  in  the
       alarm clock.
