Process

The process dialog displays information about the processes within Lisp. See multiprocessing.htm for information on processes.

Click on the Update button to update the display. It is not updated automatically.

The Headings

• Name: The name of the process
• Brk: The break level of the process. A process enters a higher break level when an error is signaled but not handled. Other conditions, when signaled, may put a process in a break level under certain circumstances (when *break-on-signals* is true, e.g.) Break level 0 means no unhandled error or condition.
• State: The state of the process (active, runnable, waiting, etc.)
• Status Note: The "whostate" of the process (as returned by process-whostate). While the value can be any string, it usually describes what the process is doing.
• Prio: The priority of the process.
• Quantum (Q... in the illustration): The process quantum.
• Time: the (approximate) total cpu time consumed by the process.
• Delta: The cpu time consumed since the last report.
• Dis: The number of times the process has been resumed since the last report.
• Profilable (P... in the illustration) A * in the column indicates the process can be profiled.
• Arrest Reasons the arrest reasons (as returned by process-arrest-reasons) of the process.

The buttons

• Update: update the display.
• Debug: display the process stack backtrace in the debug window.
• Arrest: Arrest the process for arrest reason "debugging".
• Unarrest: Remove (if possible) the arrest reasons of the process.
• Abort: Unwind the process thread clearing all errors and break levels.
• Delete: Kill (and delete) the process.
