C++ (Cpp) find_delta Examples

Example #1

File: index-pack.c Project: Pistos/git

static int find_delta_children(const union delta_base *base,
			       int *first_index, int *last_index)
{
	int first = find_delta(base);
	int last = first;
	int end = nr_deltas - 1;

	if (first < 0)
		return -1;
	while (first > 0 && !memcmp(&deltas[first - 1].base, base, UNION_BASE_SZ))
		--first;
	while (last < end && !memcmp(&deltas[last + 1].base, base, UNION_BASE_SZ))
		++last;
	*first_index = first;
	*last_index = last;
	return 0;
}

Example #2

				int *first_index, int *last_index,
				enum object_type type)
{
