Function documentation

 Default constructor
void Init()
Initialize MemStat manager - used only by instance method
TMemStatMng* GetInstance()
 GetInstance - a static function
 Initialize a singleton of MemStat manager
void Close()
 Close - a static function
 This method stops the manager,
 flashes all the buffered data and closes the output tree.
void SetBufferSize(Int_t buffersize)
 Set the maximum number of alloc/free calls to be buffered.
if the alloc and free are in the buffer, the corresponding entries
are not saved tio the Tree, reducing considerably the Tree output size
void SetMaxCalls(Int_t maxcalls)
 Set the maximum number of new/delete registered in the output Tree.
void Enable()
 Enable memory hooks
void Disable()
 Disble memory hooks
void MacAllocHook(void* ptr, size_t size)
 AllocHook - a static function
 a special memory hook for Mac OS X memory zones.
 Triggered when memory is allocated.
void MacFreeHook(void* ptr)
 AllocHook - a static function
 a special memory hook for Mac OS X memory zones.
 Triggered when memory is deallocated.
void * AllocHook(size_t size, const void* )
 AllocHook - a static function
 A glibc memory allocation hook.
void FreeHook(void* ptr, const void* )
 FreeHook - a static function
 A glibc memory deallocation hook.
Int_t generateBTID(UChar_t* CRCdigest, Int_t stackEntries, void** stackPointers)
 An internal function, which returns a bitid for a corresponding CRC digest
 cache variables
void AddPointer(void* ptr, Int_t size)
 Add pointer to table.
 This method is called every time when any of the hooks are triggered.
 The memory de-/allocation information will is recorded.
void FillTree()
loop on all entries in the buffer and fill the output Tree
entries with alloc and free in the buffer are eliminated
void SetUseGNUBuiltinBacktrace(Bool_t newVal)
stack data members
