Overview

The Call Stack view lists the function calls leading to the current program statement. The stack frame for each function call displays the function's name and its associated parameter names and values. You can traverse the stack by double-clicking on the stack frame you want to view.

When you select a stack frame, the appropriate source code is displayed in the Source and Disassembly views with a green stack marker indicating the current context. In the Watch view, the expressions are re-evaluated based on the newly selected context. In the Local Variables view, the local arguments and variables associated with the selected stack frame are displayed. In Quick Watch, you can recalculate the value of a variable expression based on the newly selected context.

You can access the Call Stack view from the main WDB GUI window by clicking the Call Stack tab in the lower tabbed area.
