NAME
     ualarm — schedule signal after specified time

SYNOPSIS
     #include <unistd.h>

     u_int
     ualarm(u_int microseconds, u_int interval);

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

     The ualarm() function waits a count of microseconds before asserting the
     terminating signal SIGALRM.  System activity or time used in processing
     the call may cause a slight delay.

     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).

RETURN VALUES
     When the signal has successfully been caught, alarm() returns the amount
     of time left on the clock.	 The maximum number of microseconds allowed is
     2147483647.
