Functions
size_t	total_size (flags< capabilities > c) noexcept
	Returns the total size of heap regions matching the given capabilities.
size_t	free_size (flags< capabilities > c) noexcept
	Returns the current free size of heap regions matching the given capabilities.
size_t	largest_free_block (flags< capabilities > c) noexcept
	Returns the largest free block in heap regions matching the given capabilities.
size_t	minimum_free_size (flags< capabilities > c) noexcept
	Returns the minimum free size since boot for heap regions matching the given capabilities.
info	get_info (flags< capabilities > c) noexcept
	Returns detailed heap statistics for regions matching the given capabilities.
template<typename F >
void	walk (flags< capabilities > c, F &&walker)
	Walk all heap blocks in regions matching the given capabilities.
template<typename F >
void	walk (F &&walker)
	Walk all heap blocks across all heaps.
bool	check_integrity (flags< capabilities > c, bool print_errors=false) noexcept
	Check integrity of heaps with the given capabilities, or all heaps.
bool	check_integrity (bool print_errors=false) noexcept
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
void	dump (flags< capabilities > c) noexcept
	Dump the structure of heaps with matching capabilities, or all heaps.
void	dump () noexcept
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
