	Init the subsystem.

bool get_stats	(	const char *	stat_type,
		int	nkey,
		ADD_STAT	add_stats,
		void *	c
	)

Return a datum for stats in binary protocol.

Here is the call graph for this function:

void* slabs_alloc	(	const size_t	size,
		unsigned int	id
	)

Allocate object of given length.

0 on error

Here is the caller graph for this function:

unsigned int slabs_clsid

(

const size_t

size

)

Given object size, return id to use when allocating/freeing memory for object 0 means error: can't store such a large object.

Here is the caller graph for this function:

void slabs_free	(	void *	ptr,
		size_t	size,
		unsigned int	id
	)

Free previously allocated object.

Here is the caller graph for this function:

void slabs_init	(	const size_t	limit,
		const double	factor,
		const bool	prealloc
	)

Init the subsystem.

1st argument is the limit on no. of bytes to allocate, 0 if no limit. 2nd argument is the growth factor; each slab will use a chunk size equal to the previous slab's chunk size times this factor. 3rd argument specifies if the slab allocator should allocate all memory up front (if true), or allocate memory in chunks as it is needed (if false)

Here is the caller graph for this function:

int slabs_reassign	(	unsigned char	srcid,
		unsigned char	dstid
	)

void slabs_stats	(	ADD_STAT	add_stats,
		void *	c
	)

Fill buffer with stats.

Here is the caller graph for this function:
