The nodes that are evaluated are specified in either in the node-pattern or in the node-id. The node-pattern parameter should contain string with a node path pattern. Node path patterns are described in the Analyzer User's Guide. The node-id parameter should contain a node-id.
If -immediately is specified, and the node condition is true when the command is issued, the command take action immediately, otherwise, the next time the node condition evaluates to true.
If a cpu is specified, this command will ignore events on all other processors. If timeout is a positive number, the command will run for at most that many seconds of virtual time.
If timeout-rt is a positive number, the command will run for at most that many seconds of real time.
A time-out will be signaled by throwing a CLI exception, which can be captured using try/except in order to take specific action, or to let it pass unhandled.
