Detailed Description

This file contains all generic CNID related stuff declarations. Included:

• CNID factory, which retrieves (eventually instantiates) CNID objects on demand
• selection of CNID backends (default, detected by volume)
• full set of CNID operations needed by server core.

Typedef Documentation

cnid_db

Function Documentation

cnid_add()

cnid_t cnid_add	(	struct _cnid_db *	cdb,
		const struct stat *	st,
		const cnid_t	did,
		const char *	name,
		const size_t	len,
		cnid_t	hint )

cnid_close()

void cnid_close

(

struct _cnid_db *

db

)

Closes CNID database. Currently it's just a wrapper around db->cnid_close().

cnid_delete()

int cnid_delete	(	struct _cnid_db *	cdb,
		cnid_t	id )

cnid_find()

int cnid_find	(	struct _cnid_db *	cdb,
		const char *	name,
		size_t	namelen,
		void *	buffer,
		size_t	buflen )

cnid_get()

cnid_t cnid_get	(	struct _cnid_db *	cdb,
		const cnid_t	did,
		char *	name,
		const size_t	len )

cnid_getstamp()

int cnid_getstamp	(	struct _cnid_db *	cdb,
		void *	buffer,
		const size_t	len )

cnid_init()

void cnid_init

(

void

)

cnid_lookup()

cnid_t cnid_lookup	(	struct _cnid_db *	cdb,
		const struct stat *	st,
		const cnid_t	did,
		char *	name,
		const size_t	len )

cnid_open()

Opens CNID database using particular back-end

cnid_rebuild_add()

cnid_t cnid_rebuild_add	(	struct _cnid_db *	cdb,
		const struct stat *	st,
		const cnid_t	did,
		char *	name,

		cnid_t	hint )

cnid_register()

void cnid_register

(
