arena(addr=None)

Print the contents of an arena, default to the current thread's arena.

arenas()

Lists this process's arenas.

bin_ascii(bs)

bin_labels_mapping(collections)

Print the contents of an arena's fastbins, default to the current thread's arena.

Find candidate fake fast chunks overlapping the specified address.

format_bin(bins, verbose=False, offset=None)

heap(addr=None, verbose=False, simple=False)
