Data Structures
struct	block
Defines
#define	BLOCK_FLAGS_NONE   0
	This macro is a symbolic value for situations where no special flags are needed.
#define	BLOCK_FLAGS_NOREAD   1
	When the client of block_get() intends to overwrite the current contents of the block, this flag is used to avoid the unnecessary read.
Enumerations
enum	cache_mode { CACHE_MODE_WT, CACHE_MODE_WB }
	Caching mode. More...
