void GetRelatedNodesMult_bn ( | nodelist_bn* related_nodes, const char* relation, const nodelist_bn* nodes )

Finds all the Nodes that bear the relationship relation with any member of nodes and puts them in related_nodes.

Otherwise it works the same as GetRelatedNodes_bn; see that function for more information.

Note: It is okay if related_nodes = nodes (i.e., the list gets modified in-place).

On entry, nodes must not contain duplicates (but related_nodes may).

Tip: A handy and efficient way to remove the duplicates from any node list is to call this function with the node list as related_nodes, an empty list for nodes, and "parents,union" as the relation.

Version:

Versions 3.05 and later have this function.

GetRelatedNodes_bn |  | Same, but for a single node
IsNodeRelated_bn |  | Tests relationship of two nodes
GetNetNodes_bn |  | Get all nodes in the net

Example:

    //find all the parents of all the children of a node
    nodelist_bn* children =  GetNodeChildren_bn (node);
    nodelist_bn* parentsOfChildren = NewNodeList2_bn (0, GetNodeNet_bn (node));
    GetRelatedNodesMult_bn (parentsOfChildren, "parents", children);

Example 2:

    //find all the descendants of the children of a node, excluding the children themselves.
    //I.e., find grand-children, great-grandchildren, great-great-grandchildren, ...
    nodelist_bn* children =  GetNodeChildren_bn (node);
    nodelist_bn* descendants = NewNodeList2_bn (0, GetNodeNet_bn (node));
    GetRelatedNodesMult_bn (descendants, "descendants,exclude_self", children);
