Figure 179: Diving on Local
Variables and Registers
Displaying Variables
The window at the top of the figure shows the result of diving on a register,
while the bottom window shows the results of diving on an array variable.
CLI: dprint variable
This command lets you view variables and expressions without having
to select or find them.
You can also display local variables by using the View > Lookup Variable
command. After TotalView displays a dialog box, enter the name of the variable
you want to see.
Dereferencing Variables Automatically
In most cases, you want to see what a pointer points to, rather than what
the value of its variable is. Using the controls on the File > Preferences
Pointer Dive Page (which is shown on the next page), you can tell TotalView
to automatically dereference pointers. (See Figure 180 on page 294.)
Dereferencing pointers is especially useful when you want to visualize the
data linked together with pointers, since it can present the data as a unified
array. Because the data appears as a unified array, you can use TotalView’s
array manipulation commands and the Visualizer to view the data.
Each pulldown list on the Pointer Dive Page has three settings: No, Yes, and
Yes (don’t push). The meaning for No is that automatic dereferencing does
not occur. The remaining two values tell TotalView to automatically dereference
pointers. The difference between the two is based on whether you
can use the Back command to see the undereferenced pointer’s value. If
