|
* This is the parameter for signal events. The {@see \Prado\TEventParameter::getParameter()} |
|
16
|
|
|
* property is the array of $signalInfo from the Signal handler {@see \Prado\Util\TSignalsDispatcher::__invoke()}; |
|

|
|
|
* when available on the PHP system. |
|
18
|
|
|
* |
|
19
|
|
|
* There is also the Signal {@see self::getSignal()}, whether to exit {@see self::getIsExit()}, |
|
20
|
|
|
* the exit code when exiting {@see self::getExitCode()}, and the alarm time {@see self::getAlarmTime()} |
|
21
|
|
|
* if the signal is SIGALRM. |
|
22
|
|
|
* |
|
23
|
|
|
* When there is Signal Info in the Parameter property, there are inspection methods |
|
24
|
|
|
* {@see self::getParameterErrorNumber()} for accessing the Signal Error Number, |
|
25
|
|
|
* {@see self::getParameterCode()} for accessing the Signal Code, {@see self::getParameterStatus()} |
|
26
|
|
|
* for accessing the Signal Status, {@see self::getParameterPID()} for accessing |
|
27
|
|
|
* the Signal PID, and {@see self::getParameterUID()} for accessing the Signal PID UID. |
