Function Documentation

builtin_return_address()

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

Definition at line 121 of file TMemStatBacktrace.cxx.

demangle()

void Memstat::demangle	(	char *	_codeInfo,
		TString &	_str
	)

demangle symbols

Definition at line 211 of file TMemStatBacktrace.cxx.

dig2bytes()

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

Definition at line 26 of file TMemStatHelpers.cxx.

find_string()

template<class T >

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

Definition at line 42 of file TMemStatHelpers.h.

getBacktrace()

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)

Definition at line 138 of file TMemStatBacktrace.cxx.

getSymbolFullInfo()

void Memstat::getSymbolFullInfo	(	void *	_pAddr,
		TString *	_retInfo,
		const char *const	_seporator = " | "
	)

Definition at line 185 of file TMemStatBacktrace.cxx.

getSymbols()

int Memstat::getSymbols	(	void *	_pAddr,
		TString &	_strInfo,
		TString &	_strLib,
		TString &	_strSymbol
	)

get the name of the function and library

Definition at line 155 of file TMemStatBacktrace.cxx.

operator<()

bool Memstat::operator< ( const SCustomDigest &  a, const SCustomDigest &  b  )

inline

Definition at line 64 of file TMemStatMng.h.

return_address()

static void * Memstat::return_address ( int  _frame )

static

we have a limit on the depth = 35
