Dave Funk mentions:

However for a quick and simple whack, try:

extern void msg_$get_my_node(
    int *node_id
);

It's not released but it's simple and relatively safe.

Another way might be:

   int  node_id ;
   sscanf( getenv( "NODEID" ), "NODEID=%x", &node_id );

Before SR10 NODEID was a "protected" environment variable that
you could count on not to change and to be correct...  At SR10
you *can* change the value of this variable but I wouldn't want
to speculate on what might or might not break...  In short it
should be fairly reliable...
