//
// class: CNetCfgDebug
//
// Purpose: In order to debug instance leaks of your class instances, you can
// derive your class from CNetCfgDebug. This adds no data members nor
// a v-table nor virtual functions to your class. It will add
// a constructor and destructor that will be called before & after yours
// respectively, in order to keep track of your class instances.
//
// This will only happen on CHK builds. On FRE builds deriving from this
// class has no effect, and is safe.
//
// Author: deonb 7 July 2001
//
// Notes:
// This is s an ATL style parent template derive, e.g.:
// CNetCfgDbg<parent>
// e.g.
//
// class CConnectionManager : public ClassX,
// public classY,
// public CNetCfgBase<CConnectionManager>
//
// No other interaction with your class is needed. This will now automatically
// keep a list of all the instances allocated of this class (in debug mode),
// with a stack trace where they were allocated from. This is a Tracing
// stack trace so it's only successful for functions inside the callstack which
// actually used a TraceXxx statement (any trace statement) before they called
// the child functions.
//
// e.g.
// void X()
// {
// TraceFileFunc(ttidSomething);
// void Y()
// {
// void Z()
// {
// TraceTag(ttidSomething, "allocation class");
// CConnectionManager *pConnectionManager = new CConnectionManager();
// }
// TraceTag(ttidSomething, "Z called");
// }
// }
//
// This will spew the following when the process terminates (or when TraceAllocatedObjects is called):
// ASSERT: "An object leak has been detected. Please attach a user or kernel mode debugger and hit
// IGNORE to dump the offending stacks"
//
// The object of type 'class CConnectionManager' allocated at 0x7fe2345 has not been freed:
// it was constructed from the stack below:
// Z [EBP: 0x731d3128] 0x00000001 0x00000000 0x0000000a
// X [EBP: 0x731d310f] 0x0000000f 0x0000000e 0x0000000a
//
// (since Y() did not contain a trace statement before the call to Z() )
//
