size_t Memstat::builtin_return_address	(	void **	_container,
		size_t	_limit
	)

Definition at line 121 of file TMemStatBacktrace.cxx.

void Memstat::demangle	(	char *	_codeInfo,

	)

demangle symbols

string Memstat::dig2bytes

(

Long64_t

bytes

)

This function creates a string representation of the number of bytes, represented as a number in B, kB, MB or GB depending on the value.

The result is rounded to a sensible number of digits

template<class T >

Int_t Memstat::find_string	(	const T &	_Container,
		const TString &	_ToFind
	)

Definition at line 42 of file TMemStatHelpers.h.

size_t Memstat::getBacktrace	(	void **	_trace,
		size_t	_size,
		Bool_t	_bUseGNUBuiltinBacktrace
	)

Get the backtrace _trace - array of pointers _size - maximal deepness of stack information _bUseGNUBuiltinBacktrace - whether to use gcc builtin backtrace or C library one.

The builtin version is much faster, but very sensitive and in some conditions could fail to return a proper result. return value = min(stack deepness, dsize)
