ualarm(3C)							    ualarm(3C)

NAME    [Toc]    [Back]

     ualarm - generate a SIGALRM signal	in ``useconds''	microseconds

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     useconds_t	ualarm (useconds_t useconds, useconds_t	interval);

DESCRIPTION    [Toc]    [Back]

     The ualarm() function causes the SIGALRM 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
     nonzero, repeated timeout notification occurs with	a period in
     microseconds specified by the interval argument.  If the notification
     signal, SIGALRM, is not caught or ignored,	the calling process is
     terminated.

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