Many debuggers support outputting real-time call-stack
information, in this example we use list to output real-time
calling stack information in C++. To use it, you just need:
(1) add class and macro to you project;
(2) use MACRO CALL_BACK（） in the top of your function, for
example:
void myfunction(int a, int b)
{
CALL_BACK( void myfunction(int
a, int b));
