ITIMERFIX(9)           NetBSD Kernel Developer's Manual           ITIMERFIX(9)


NAME

     itimerfix -- check that a timeval value is valid, and correct


SYNOPSIS

     #include <sys/time.h>

     int
     itimerfix(struct timeval *tv);


DESCRIPTION

     The itimerfix function checks that the value in tv is valid (0 <=
     tv->tv_sec &&  0 <= tv->tv_usec < 1000000), and that the total time rep-
     resented is at least one tick, or zero.

     If the total represented time is nonzero and smaller than tick, it is
     adjusted to exactly one tick.


RETURN VALUES

     itimerfix returns 0 on success or EINVAL if tv is invalid.
