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_validate_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.
