in the Tools > Expression
List Window
Viewing a List of Variables
In a similar fashion, you can even directly enter functions. (See Figure 197.)
Using the Expression List with Multi-process/Multithreaded
Programs
You can change the thread in which TotalView evaluates your expressions
by typing a new thread value in the Threads box at the top of the window. A
second method is to select a value by using the drop-down list in the
Threads box.
When you use an Add to Expression List command, TotalView checks
whether an Expression List Window is already open for the current thread.
If one is open, TotalView adds the variable to the bottom of the list. If an
Expression List Window isn’t associated with the thread, TotalView duplicates
an existing window, changes the thread of the duplicated window,
and then adds the variable to all open Tools > Expression List Windows.
That is, you have two Tools > Expression List Windows. Each has the same
list of expressions. However, the results of the expression evaluation differ
because TotalView is evaluating them in different threads.
In all cases, the list of expressions in all Tools > Expression List Windows is
the same. What differs is the thread in which TotalView evaluates the window’s
expressions.
Similarly, if TotalView is displaying two or more Tools > Expression List Windows,
and you send a variable from yet another thread, TotalView adds the
variable to all of them, duplicates one of them, and then changes the
thread of the duplicated window.
Reevaluating, Reopening, Rebinding, and Restarting
This section explains what happens in the Tools > Expression List Window
as TotalView performs various operations.
Reevaluating Contents: TotalView reevaluates the value of everything
in the Tools > Expression List Window Expression column whenever your
thread stops executing. More precisely, if a thread stops executing,
TotalView reevaluates the contents of all Tools > Expression List Windows
associated with the thread. In this way, you can see how the values of these
expressions change as your program executes.
