vg4->nodelink->get()

Get linked nodes of a node.

SYNTAX

int vg4->nodelink->get(struct VG_Nodelink *ndlnk, const char *nodeid, const char ***linkids, VG_BOOL withdeact)

FUNCTION PARAMETERS

ndlnk	Nodelink
nodeid	Node
linkids	For returning linked nodes, must be freed with free()
withdeact	Whether ignore deactivation of links

RETURN VALUE

Returns number of nodes in linkids

DESCRIPTION

Get linked nodes of a node. Links deactivated by vg4->nodelink->deactivate() will be ignored. With withdeact set to VG_TRUE, a possible deactivation of nodeid to another linked node is ignored.

EXAMPLE

/* get activated linked nodes of NODE1 */
const char **linkids;
int nlink, i1;

nlink = vg4->nodelink->get(ndlnk, "NODE1", &linkids, VG_FALSE);
if (nlink > 0) {
  for (i1 = 0; i1 < nlink; i1++) {
    printf("%s\n", linkids[i1]);
  }
  free(linkids);
}
