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); Descriptioniv_now is a global variable that reflects the current time-of-day. Applications written to the ivykis API generally require to know the current time-of-day in many places, and therefore effort is done to cache this quantity. The contents of…
