C++ (Cpp) tmv_add Examples

Example #1

File: mave.c Project: HuangFeiFelix/linuxptp

tmv_t mave_accumulate(struct mave *m, tmv_t val)
{
	m->sum = tmv_sub(m->sum, m->val[m->index]);
	m->val[m->index] = val;
	m->index = (1 + m->index) % m->len;
	m->sum = tmv_add(m->sum, val);
	if (m->cnt < m->len) {
		m->cnt++;
	}
	return tmv_div(m->sum, m->cnt);
}

Example #2

File: tsproc.c Project: HeXingxing/linuxptp-as
