# CallStack Class Reference

`#include <wait.h>`

Inheritance diagram for CallStack:

List of all members.

## Detailed Description

A simple unidirectional linked list with m_prev == 0 to indicate the final entry. The aim of this implementation is to provide a very lightweight and practical tracing mechanism with a low performance impact. Functions and methods supporting this call-stack mechanism would take a parameter of the form "CallStack const& callStack", and would pass this parameter to subsequent functions they call using the construct:

SubFunc(arg1, arg2, CallStack("my func at place such and such", &callStack));

The advantage of this approach is that it is easy to use and should be very efficient, involving no allocation from the heap, just a linked list of stack objects containing pointers to static ASCIIZ strings (or possibly additional but simple data if derived).
