#define OFORK_HASHSIZE   64

Function Documentation

hashfn()

unsigned long hashfn ( const struct file_key * key )

static

of_ad()

struct adouble * of_ad	(	const struct vol *	vol,
		struct path *	path,
		struct adouble *	ad )

of_alloc()

struct ofork * of_alloc	(	struct vol *	vol,
		struct dir *	dir,
		char *	path,
		uint16_t *	ofrefnum,
		const int	eid,
		struct adouble *	ad,
		struct stat *	st )

of_close_all_forks()

void of_close_all_forks

(

const AFPObj *

obj

)

close all forks

of_closefork()

int of_closefork	(	const AFPObj *	obj,
		struct ofork *	ofork )

of_closevol()

void of_closevol	(	const AFPObj *	obj,
		const struct vol *	vol )

close all forks for a volume

of_dealloc()

void of_dealloc

(

struct ofork *

of

)

of_find()

struct ofork * of_find

(

const uint16_t

ofrefnum

)

of_findname()

struct ofork * of_findname	(	const struct vol *	vol,
		struct path *	path )

of_findnameat()

struct ofork * of_findnameat	(	int	dirfd,
		struct path *	path )

Search for open fork by dirfd/name.

Function call of_fstatat with dirfd and path and uses dev and ino to search the open fork table.

Parameters

[in]	dirfd	directory fd
[in,out]	path	pointer to struct path

of_flush()

int of_flush

(

const struct vol *

vol

)

of_fstatat()

int of_fstatat	(	int	dirfd,
		struct path *	path )

of_hash()

void of_hash ( struct ofork * of )

static

of_pforkdesc()

void of_pforkdesc

(

FILE *

f

)

of_rename()

int of_rename	(	const struct vol *	vol,
		struct ofork *	s_of,
		struct dir *	olddir,
		const char *	oldpath,
		struct dir *	newdir,
		const char *	newpath )

of_stat()

int of_stat	(	const struct vol *	vol,
		struct path *	path )

of_statdir()

int of_statdir	(	struct vol *	vol,
		struct path *	path )

stat the current directory.

Note

stat(".") works even if "." is deleted thus we have to stat ../name because we want to know if it's there

of_unhash()

void of_unhash ( struct ofork * of )

static
