Displaying Variables Figure 175: Variable Window Showing Frozen State Figure 176: Locked and Unlocked Variable Windows View > Lock Address command. Figure 176 shows two Variable Windows, one of which has had its address locked. Using this command lets you continually reevaluate what is at that address as execution progresses. Here are two examples: � If you need to look at a heap address access through a set of dive operations rooted in a stack frame that has become stale. � If you dive on a *this pointer to see the actual value after *this goes stale. 290 Chapter 14: Examining and Changing Data
Figure 177: Program Browser and Variable Windows (Part 1) Browsing for Variables Displaying Variables The Process Window Tools > Program Browser command displays a window that contains all your executable’s components. By clicking on a library or program name, you can access all of the variables contained in it. (See Figure 177.) The window at the top of the figure shows programs and libraries that are loaded. If you have loaded more than one program with the File > New Program command, TotalView only displays information for the currently selected process. After diving on an entry in this window (labelled Dive 1), TotalView displays a Variable Window that contains a list of files that make up the program, as well as other related information. Diving on an entry in this Variable Window (Dive 2 in this figure) changes the display so that it contains variables and other information related to the file. A list of functions defined within the program is at the end of this list. Diving on a function changes the Variable Window again. The window shown at the top of the next figure was created by diving on one of these functions. The window shown in the center is the result of diving on a block in that subroutine. The bottom window shows a variable. (See Figure 178 on page 292.) TotalView Users Guide: version 8.7 291
