C++ (Cpp) close_cr_imgset Examples

Example #1

File: image.c Project: Open-Party/criu

struct cr_imgset *cr_imgset_open_range(int pid, int from, int to,
			       unsigned long flags)
{
	struct cr_imgset *imgset;

	if (!imgset)
		goto err;

	from++;
	imgset->fd_off = from;
	for (i = from; i < to; i++) {
		struct cr_img *img;

		img = open_image(i, flags, pid);
		if (!img) {
			if (!(flags & O_CREAT))
				/* caller should check himself */
				continue;
			goto err;
		}

		imgset->_imgs[i - from] = img;
	}

	return imgset;

err:
	close_cr_imgset(&imgset);
	return NULL;
}

Example #2

File: ipc_ns.c Project: 8472/criu

{
	int ret;
	struct cr_imgset *imgset;

	imgset = cr_imgset_open(ns_id, IPCNS, O_DUMP);
	if (imgset == NULL)
		return -1;

	ret = dump_ipc_data(imgset);
	if (ret < 0) {
		pr_err("Failed to write IPC namespace data\n");
		goto err;
	}

err:
	close_cr_imgset(&imgset);
	return ret < 0 ? -1 : 0;
