Collaboration diagram for mem:

Data Fields
mem_size_t	next

mem_size_t	prev

u8_t	used

u8_t	pad [3]

Detailed Description

The heap is made up as a list of structs of this type. This does not have to be aligned since for getting its size, we only use the macro SIZEOF_STRUCT_MEM, which automatically alignes.
