Function Documentation

int nvwa::check_leaks

(

)

Checks for memory leaks.

Returns:

zero if no leakage is found; the number of leaks otherwise

int nvwa::check_mem_corruption

(

)

Checks for heap corruption.

Returns:

zero if no problem is found; the number of found memory corruptions otherwise

pctimer_t nvwa::pctimer

void

template<class _Tp , class _Alloc >

void nvwa::swap	(	fc_queue< _Tp, _Alloc > &	lhs,
		fc_queue< _Tp, _Alloc > &	rhs
	)			[inline]

Exchanges the elements of two queues.

Parameters:

	lhs	the first queue to exchange
	rhs	the second queue to exchange

Postcondition:

If swapping the allocators does not throw, lhs will be swapped with rhs. If swapping the allocators throws with strong exception safety guarantee, this function will also provide such guarantee.

void nvwa::swap	(	bool_array &	lhs,
		bool_array &	rhs
	)			[inline]

Exchanges the content of two bool_arrays.

Parameters:

	lhs	the first bool_array to exchange
	rhs	the second bool_array to exchange

Variable Documentation

bool nvwa::new_autocheck_flag = true

Flag to control whether check_leaks will be automatically called on program exit.

FILE * nvwa::new_output_fp = stderr

Pointer to the output stream.

The default output is stderr, and one may change it to a user stream if needed (say, new_verbose_flag is true and there are a lot of (de)allocations).

const char * nvwa::new_progname = _DEBUG_NEW_PROGNAME

Pointer to the program name.

Its initial value is the macro _DEBUG_NEW_PROGNAME. You should try to assign the program path to it early in your application. Assigning argv[0] to it in main is one way. If you use bash or ksh (or similar), the following statement is probably what you want: `new_progname = getenv("_");'.

bool nvwa::new_verbose_flag = false

Flag to control whether verbose messages are output.

const size_t nvwa::PLATFORM_MEM_ALIGNMENT = sizeof(size_t) * 2

The platform memory alignment.

The current value works well in platforms I have tested: Windows XP, Windows 7 x64, and Mac OS X Leopard. It may be smaller than the real alignment, but must be bigger than sizeof(size_t) for it work. nvwa::debug_new_recorder uses it to detect misaligned pointer returned by `new NonPODType[size]'.
