Function Documentation

struct __attribute__

(

(__packed__)

)

Contains information about inode.

Main inode struct.

This struct contains info that can be simply written to memory

This struct represent inode

Definition at line 19 of file inode.h.

void destroy_inode

(

struct inode *

inode

)

Destructor of inode.

Parameters

inode

Definition at line 44 of file inode.c.

void init_inode	(	struct inode *	inode,
		uint16_t	id,
		bool	is_file,
		const struct superblock *	superblock
	)

Constructor of inode.

Parameters

inode	empty instance of inode
id	id of inode
is_file

Definition at line 34 of file inode.c.

ssize_t read_inode	(	int	fd,
		struct inode *	inode,
		uint16_t	inode_id,
		const struct superblock *	superblock
	)

Read inode from memory.

Parameters

fd	opened fd
inode	empty instance of inode
inode_id	id of inode to read
superblock	the superblock with metadata of FS

Returns

sizeof(inode) if reading is ok; -1 otherwise and destruct inode object

Warning

printf strerror(errno) to stderr

Definition at line 49 of file inode.c.

size_t sizeof_inode

(

const struct superblock *

superblock

)

Count size of inode in bytes.

Parameters

superblock

the superblock with metadata of FS

Returns

size of inode in FS

uint16_t sizeof_inodes_block

(

const struct superblock *

superblock

)

Calculate size of block of all inodes.

Parameters

superblock

Returns

Definition at line 111 of file inode.c.

ssize_t write_inode	(	int	fd,
		struct inode *	inode,
		const struct superblock *	superblock
	)

Write inode from memory.

Parameters

fd	opened fd
inode	instance of inode
superblock	the superblock with metadata of FS

Returns
