C++ (Cpp) nvlist_xdescriptors Examples

Example #1

File: nvlist.c Project: BillTheBest/libuinet

static int *
nvlist_xdescriptors(const nvlist_t *nvl, int *descs, int level)
{
	const nvpair_t *nvp;

	NVLIST_ASSERT(nvl);
	PJDLOG_ASSERT(nvl->nvl_error == 0);
	PJDLOG_ASSERT(level < 3);

	for (nvp = nvlist_first_nvpair(nvl); nvp != NULL;

			*descs = nvpair_get_descriptor(nvp);
			descs++;
			break;
		case NV_TYPE_NVLIST:
			descs = nvlist_xdescriptors(nvpair_get_nvlist(nvp),
			    descs, level + 1);
			break;
		}
	}

	return (descs);

Example #2

{
	size_t nitems;
	int *fds;

	nitems = nvlist_ndescriptors(nvl);
	fds = nv_malloc(sizeof(fds[0]) * (nitems + 1));
	if (fds == NULL)
		return (NULL);
	if (nitems > 0)
		nvlist_xdescriptors(nvl, fds);
	fds[nitems] = -1;
	if (nitemsp != NULL)
		*nitemsp = nitems;
	return (fds);
