###
Data Types

####
cookie() = atom()

###
Exports

####
cookie() -> Cookie

### Types

Cookie = cookie()

Use erlang:get_cookie() in ERTS instead.

####
cookie(TheCookie) -> true

### Types

TheCookie = Cookie | [Cookie]
The cookie can also be specified as a list with a single atom element.
Cookie = cookie()

Use erlang:set_cookie(node(), Cookie) in ERTS instead.

####
is_auth(Node) -> yes | no

### Types

Node = node()

Returns yes if communication with Node is authorized. Notice that a connection to Node is established in this case. Returns no if Node does not exist or communication is not authorized (it has another cookie than auth thinks it has).

Use net_adm:ping(Node) instead.

####
node_cookie([Node, Cookie]) -> yes | no

### Types

Node = node()
Cookie = cookie()

Equivalent to node_cookie(Node, Cookie).

####
node_cookie(Node, Cookie) -> yes | no

### Types

Node = node()
Cookie = cookie()

Sets the magic cookie of Node to Cookie and verifies the status of the authorization. Equivalent to calling erlang:set_cookie(Node, Cookie), followed by auth:is_auth(Node).
