iv_time(3)		  ivykis programmer's manual		    iv_time(3)

NAME
       iv_now, iv_validate_now,	iv_invalidate_now - ivykis time	handling

SYNOPSIS
       #include	<iv.h>

       extern struct timespec iv_now;
       void iv_validate_now(void);
       void iv_invalidate_now(void);

DESCRIPTION
       iv_now is a global variable that	represents a monotonic timer.

       The  contents  of iv_now	might be stale.	 Calling the function iv_vali-
       date_now	ensures	that the current contents of iv_now are	up-to-date.

       The function iv_invalidate_now is called	to  invalidate	the  currently
       cached  time.   This function should be called after any	operation that
       takes a significant amount of wall clock	time.
