int ubifs_add_snod	(	const struct ubifs_info *	c,
		struct ubifs_scan_leb *	sleb,
		void *	buf,
		int	offs
	)

ubifs_add_snod - add a scanned node to LEB scanning information. : UBIFS file-system description object : scanning information : buffer containing node : offset of node on flash

This function returns %0 on success and a negative error code on failure.

void ubifs_end_scan	(	const struct ubifs_info *	c,
		struct ubifs_scan_leb *	sleb,
		int	lnum,
		int	offs
	)

ubifs_end_scan - update LEB scanning information at end of scan. : UBIFS file-system description object : scanning information : logical eraseblock number : offset to start at (usually zero)

This function returns %0 on success and a negative error code on failure.

ubifs_scan - scan a logical eraseblock. : UBIFS file-system description object : logical eraseblock number : offset to start at (usually zero) : scan buffer (must be of ->leb_size bytes in size) : print no messages

This function scans LEB number and returns complete information about its contents. Returns the scaned information in case of success and, %-EUCLEAN if the LEB neads recovery, and other negative error codes in case of failure.

If is non-zero, this function does not print large and scary error messages and flash dumps in case of errors.

	)

ubifs_scan_a_node - scan for a node or padding. : UBIFS file-system description object : buffer to scan : length of buffer : logical eraseblock number : offset within the logical eraseblock : print no messages

This function returns a scanning code to indicate what was scanned.
