27 getnodes() fills the array, nodes, with no more than nnodes node iden‐
28 tifiers whose types match nodetype at the bit positions specified by
29 typemask. Given sufficient space and a sufficiently large nnodes, all
30 node identifiers having a node type field that satisfies the relation
31 imposed by the nodetype and typemask arguments will be returned.
32
33 The remaining functions are wrappers for getnodes() that match commonly
34 used node types.

36 getotbs() OTB nodes
37
38 getall() all nodes
39
40 getcomps() nodes in main computing group (see getntype(2))
41
42 getjones() neighbour nodes of the caller
43
44 The node type is a combination of flags, defined in <net.h>, describing
45 the capabilities of the node. Usage of the nodetype and typemask argu‐
46 ments in getnodes() is identical to getntype(2). Indeed, getntype(2)
47 is usually called before getnodes() to count the matching nodes and
48 thus ascertain the space requirement for the node array. No indication
49 of the number of returned node identifiers is given by getnodes().
