Common Test specific layer on Erlang/OTP rpc.

 app_node(App, Candidates) -> NodeName From a set of candidate nodes determines which of them is running the application App. App = atom() Candidates = [NodeName] NodeName = atom()

From a set of candidate nodes determines which of them is running the application App. If none of the candidate nodes is running App, the function makes the test case calling this function to fail. This function is the same as calling app_node(App, Candidates, true).

 app_node(App, Candidates, FailOnBadRPC) -> NodeName Same as app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point. App = atom() Candidates = [NodeName] NodeName = atom() FailOnBadRPC = true | false

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

 app_node(App, Candidates, FailOnBadRPC, Cookie) -> NodeName Same as app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point. App = atom() Candidates = [NodeName] NodeName = atom() FailOnBadRPC = true | false Cookie = atom()

Same as ct_rpc:app_node/2, except that argument FailOnBadRPC determines if the search for a candidate node is to stop if badrpc is received at some point.

The cookie on the client node is set to Cookie for this rpc operation (used to match the server node cookie).

 call(Node, Module, Function, Args) -> term() | {badrpc, Reason} Same as call(Node, Module, Function, Args, infinity).

Same as call(Node, Module, Function, Args, infinity).

 call(Node, Module, Function, Args, TimeOut) -> term() | {badrpc, Reason} Evaluates apply(Module, Function, Args) on the node Node. Node = NodeName | {Fun, FunArgs} Fun = function() FunArgs = term() NodeName = atom() Module = atom() Function = atom() Args = [term()] Reason = timeout | term()

Evaluates apply(Module, Function, Args) on the node Node. Returns either whatever Function returns, or {badrpc, Reason} if the remote procedure call fails. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.

 call(Node, Module, Function, Args, TimeOut, Cookie) -> term() | {badrpc, Reason} Evaluates apply(Module, Function, Args) on the node Node. Node = NodeName | {Fun, FunArgs} Fun = function() FunArgs = term() NodeName = atom() Module = atom() Function = atom() Args = [term()] Reason = timeout | term() Cookie = atom()

Evaluates apply(Module, Function, Args) on the node Node. Returns either whatever Function returns, or {badrpc, Reason} if the remote procedure call fails. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.

The cookie on the client node is set to Cookie for this rpc operation (used to match the server node cookie).

 cast(Node, Module, Function, Args) -> ok Evaluates apply(Module, Function, Args) on the node Node. Node = NodeName | {Fun, FunArgs} Fun = function() FunArgs = term() NodeName = atom() Module = atom() Function = atom() Args = [term()] Reason = timeout | term()

Evaluates apply(Module, Function, Args) on the node Node. No response is delivered and the process that makes the call is not suspended until the evaluation is completed as in the case of call/3,4. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.

 cast(Node, Module, Function, Args, Cookie) -> ok Evaluates apply(Module, Function, Args) on the node Node. Node = NodeName | {Fun, FunArgs} Fun = function() FunArgs = term() NodeName = atom() Module = atom() Function = atom() Args = [term()] Reason = timeout | term() Cookie = atom()

Evaluates apply(Module, Function, Args) on the node Node. No response is delivered and the process that makes the call is not suspended until the evaluation is completed as in the case of call/3,4. If Node is {Fun, FunArgs}, applying Fun to FunArgs is to return a node name.
