Call Stack window
In this section:
The Call Stack window is available from the View menu.

This window displays the C function call stack with the current function at the top. To inspect a function call, double-click it. C-SPY now focuses on that call frame instead.
If the next Step Into command would step to a function call, the name of the function is displayed in the gray bar at the top of the window. This is especially useful for implicit function calls, such as C++ constructors, destructors, and operators.
