Functions
void	malloc_monitor_add (void *ptr, size_t size, uinttxtptr_t pc, char *func_prefix)
	Record malloc/calloc/realloc call increasing heap usage.
void	malloc_monitor_rm (void *ptr, uinttxtptr_t pc)
	Record free/realloc call decreasing heap usage.
void	malloc_monitor_mv (void *ptr_old, void *ptr_new, size_t size_new, uinttxtptr_t pc)
	Record realloc call either increasing or decreasing heap usage.

Function Documentation

malloc_monitor_add()

void malloc_monitor_add	(	void *	ptr,
		size_t	size,
		uinttxtptr_t	pc,
		char *	func_prefix )

Record malloc/calloc/realloc call increasing heap usage.

Parameters

[in]	ptr	pointer to newly allocated memory
[in]	size	size of newly allocated memory
[in]	pc	PC of calling function
[in]	func_prefix	prefix identifying memory function, one of "m","c","re"

malloc_monitor_mv()

void malloc_monitor_mv	(	void *	ptr_old,
		void *	ptr_new,
		size_t	size_new,
		uinttxtptr_t	pc )

Record realloc call either increasing or decreasing heap usage.

Parameters

[in]	ptr_old	pointer to previously allocated memory
[in]	ptr_new	pointer to newly allocated memory
[in]	size_new	size of newly allocated memory
[in]	pc	PC of calling function

malloc_monitor_rm()

void malloc_monitor_rm	(	void *	ptr,
		uinttxtptr_t	pc )

Record free/realloc call decreasing heap usage.

Parameters

[in]	ptr	pointer to memory that is being freed
[in]	pc	PC of calling function
