|
.Fl -hidden
|
|
allows creating the node which can be connected to a specific node escaping redundant connections.
|
|
.Pp
|
|
The function
|
|
.Sy :erlang.nodes/0

|
allows getting the list of nodes connected to the target node, however the list won't include hidden nodes. Depending on the input parameter, the function

|
|
Gives a node a long name and starts it. Long names take the form of
|
|
.Ar name Ns
|
