Returns

a file id

		char *	rbuf,
		size_t *	rbuflen )

afp_resolveid()

int afp_resolveid	(	AFPObj *	obj,
		char *	ibuf,
		size_t	ibuflen,
		char *	rbuf,
		size_t *	rbuflen )

resolve a file id

check_attrib()

int check_attrib ( const struct vol * vol, struct adouble * adp )

static

copy_path_name()

int copy_path_name	(	const struct vol *	vol,
		char *	newname,
		char *	ibuf )

copyfile()

int copyfile	(	struct vol *	s_vol,

		int	sfd,
		char *	src,
		char *	dst,
		char *	newname,
		struct adouble *	adp )

Note

if newname is NULL (from directory.c) we don't want to copy the resource fork. because we are doing it elsewhere. currently if newname is NULL then adp is NULL.

default_type()

		struct adouble *	adp,
		const struct stat *	st,
		const cnid_t	did,
		const char *	upath,
		const int	len )

Rename a file, including its resource fork and mac name.

renamefile and copyfile take the old and new unix pathnames and the new mac name.

Parameters

vol	volume structure
ddir	dest dir structure
sdir_fd	source dir fd to which src path is relative (for openat et al semantics) passing -1 means this is not used, src path is a full path
