Function Documentation

sys_ea_attrname_invalid()

static int sys_ea_attrname_invalid ( const char *  func, const char *  attruname  )

static

sys_ea_copyfile()

int sys_ea_copyfile	(	const struct vol *	vol,
		int	sfd,
		const char *	src,
		const char *	dst
	)

copy EAs

Parameters

[in]	vol	current volume
[in]	sfd	source file descriptor
[in]	src	source path
[in]	dst	destination path

Returns

AFP code AFP_OK on success or appropriate AFP error code

Note

Copies EAs from source file to dest file.

sys_get_eacontent()

int sys_get_eacontent	(	const struct vol *	vol,
		char *	rbuf,
		size_t *	rbuflen,
		const char *	uname,
		int	oflag,
		const char *	attruname,
		int	maxreply,
		int	fd
	)

copy native EA into rbuf

Parameters

[in]	vol	current volume
[out]	rbuf	DSI reply buffer
[in,out]	rbuflen	current length of data in reply buffer
[in]	uname	filename
[in]	oflag	link and create flag
[in]	attruname	name of attribute
[in]	maxreply	maximum EA size as of current specs/real-life
[in]	fd	file descriptor

Returns

AFP code: AFP_OK on success or appropriate AFP error code

Note

Copies EA into rbuf. Increments *rbuflen accordingly.

sys_get_easize()

int sys_get_easize	(	const struct vol *	vol,
		char *	rbuf,
		size_t *	rbuflen,
		const char *	uname,
		int	oflag,
		const char *	attruname,
		int	fd
	)

get size of a native EA

Parameters

[in]	vol	current volume
[out]	rbuf	DSI reply buffer
[in,out]	rbuflen	current length of data in reply buffer
[in]	uname	filename
[in]	oflag	link and create flag
[in]	attruname	name of attribute
[in]	fd	file descriptor

Returns

AFP code: AFP_OK on success or appropriate AFP error code

Note

Copies EA size into rbuf in network order. Increments *rbuflen +4.

sys_list_eas()

int sys_list_eas	(	const struct vol *	vol,
		char *	attrnamebuf,
		size_t *	buflen,
		const char *	uname,
		int	oflag,
		int	fd
	)

copy names of native EAs into attrnamebuf

Parameters

[in]	vol	current volume
[out]	attrnamebuf	store names a consecutive C strings here
[in,out]	buflen	length of names in attrnamebuf
[in]	uname	filename
[in]	oflag	link and create flag
[in]	fd	file descriptor

Returns

AFP code: AFP_OK on success or appropriate AFP error code

Note

Copies names of all EAs of uname as consecutive C strings into rbuf. Increments *rbuflen accordingly. We hide the adouble:ea extended attributes here, we do not allow reading, writing and deleting them.

sys_remove_ea()

int sys_remove_ea	(	const struct vol *	vol,
		const char *	uname,
		const char *	attruname,
		int	oflag,
		int	fd
	)

remove a native EA

Parameters

[in]	vol	current volume
[in]	uname	filename
[in]	attruname	EA name
[in]	oflag	link and create flag
[in]	fd	file descriptor

Returns

AFP code: AFP_OK on success or appropriate AFP error code

Note

Removes EA attruname from file uname.

sys_set_ea()

int sys_set_ea	(	const struct vol *	vol,
		const char *	uname,
		const char *	attruname,
		const char *	ibuf,
		size_t	attrsize,
		int	oflag,
		int	fd
	)

set a native EA

Parameters

[in]	vol	current volume
[in]	uname	filename
[in]	attruname	EA name
[in]	ibuf	buffer with EA content
[in]	attrsize	length EA in ibuf
[in]	oflag	link and create flag
[in]	fd	file descriptor

Returns
