The Root Window displays a list of all the processes and threads being debugged. Before your program begins executing, the Root Window contains only the name of the program being debugged. As your program creates processes and threads, they are added to this list. Associated with each is a name, location (if a remote process), process ID, status, and a list of executing threads for each process. It also shows the thread ID, status, and the routine being executed in each thread.
Figure 110 shows the Root Window for an executing multi-threaded multi-process program.
