-/*! 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). */
