Posted: Sat Nov 17, 2007 10:28 pm Post subject: Tree display of the UNIX process table and children process
Tree display of the UNIX process table - a click on a node expands the sub-tree of it's children processes
Code:
REPORT ZCPUTREE LINE-SIZE 255 NO STANDARD PAGE HEADING.
************************************************************************
* This program displays the UNIX process table as a tree. A click
* on a node (process) will expand the tree and display it's children
* processes. Along with the processes names the process id, owner
* and consumed CPU time is displayed as well. The heart of the program
* is the FIND_CHILD recursive function module, that creates the
* parent/child tree based upon the pid and ppid
************************************************************************
