Tracepoint Passcounts

passcount [n [num]]

Set the passcount of a tracepoint. The passcount is a way to automatically stop a trace experiment. If a tracepoint's passcount is n, then the trace experiment will be automatically stopped on the n'th time that tracepoint is hit. If the tracepoint number num is not specified, the passcount command sets the passcount of the most recently defined tracepoint. If no passcount is given, the trace experiment will run until stopped explicitly by the user. Examples:

() passcount 5 2 // Stop on the 5th execution of tracepoint 2

() passcount 12  // Stop on the 12th execution of the
                                // most recently defined tracepoint.
() trace foo
() pass 3
() trace bar
() pass 2
() trace baz
() pass 1        // Stop tracing when foo has been
                                 // executed 3 times OR when bar has
                                 // been executed 2 times
                                 // OR when baz has been executed 1 time.
