Function Documentation

time_cmp()

int time_cmp	(	const struct timespec *	t1,
		const struct timespec *	t2
	)

Compare two timespec structures.

Parameters

t1	first timespec
t2	second timespec

Returns

0 if equal, 1 if t1 > t2, -1 if t1 < t2

time_sub()

struct timespec time_sub	(	const struct timespec *	t1,
		const struct timespec *	t2
	)

Subtract one timespec from another.

Parameters

t1	timespec 1
t2	timespec 2

Returns

The difference between t1 and t2
