4D's internal processes have a negative type value and processes generated by the user have a positive value. Worker processes launched by user have type 5.

Here is an example of output object:


{
"number": 4,
"name": "Application process",
"sessionID": "3C81A8D7AFE64C2E9CCFFCDC35DC52F5",
"ID": 4,
"visible": true,
"type": -18,
"state": 0,
"creationDateTime": "2024-09-22T12:46:39.787Z",
"preemptive": false,
"systemID": "123145476132864",
"cpuUsage": 0,
"cpuTime": 0.006769
}

例題

You want to know if the process is preemptive:


var $preemptive : Boolean
$preemptive:=Process info(Current process).preemptive
