# 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 represented 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.
