Process:getProcess

Method

Purpose

On Linux, returns a process table filtered by the Process Name argument.

Remarks

The argument is treated as a pattern to match. If no argument string is given, all processes are returned.

Type

Synchronous, IMPACT_INFO.

Arguments

 

Name	Type	Description
Process Name	String	Process name. Empty argument returns information for all processes.
