GETNODES(2)		      LAM NETWORK LIBRARY		   GETNODES(2)

NAME
       getnodes - Get array of LAM node identifiers.

C SYNOPSIS
       #include <net.h>

       int getnodes (int *nodes, int nnodes, int nodetype, int typemask);
       int getall (int *nodes, int nnodes);
       int getcomps (int *nodes, int nnodes);
       int getjones (int *nodes, int nnodes);
       int getotbs (int *nodes, int nnodes);

FORTRAN SYNOPSIS
       subroutine GNODES (nodes, nnodes, nodetype, typemask, ierror)
       subroutine GALL (nodes, nnodes, ierror)
       subroutine GCOMPS (nodes, nnodes, ierror)
       subroutine GJONES (nodes, nnodes, ierror)
       subroutine GOTBS (nodes, nnodes, ierror)

       integer nodes(*), nnodes, nodetype, typemask, ierror

DESCRIPTION
       getnodes()  fills the array, nodes, with no more than nnodes node iden‐
       tifiers whose types match nodetype at the bit  positions	 specified  by
       typemask.   Given sufficient space and a sufficiently large nnodes, all
       node identifiers having a node type field that satisfies	 the  relation
       imposed by the nodetype and typemask arguments will be returned.

       The remaining functions are wrappers for getnodes() that match commonly
       used node types.

       getotbs()   OTB nodes

       getall()	   all nodes

       getcomps()  nodes in main computing group (see getntype(2))

       getjones()  neighbour nodes of the caller

       The node type is a combination of flags, defined in <net.h>, describing
       the capabilities of the node.  Usage of the nodetype and typemask argu‐
       ments in getnodes() is identical to getntype(2).	  Indeed,  getntype(2)
       is  usually  called  before  getnodes() to count the matching nodes and
       thus ascertain the space requirement for the node array.	 No indication
       of the number of returned node identifiers is given by getnodes().
