Function Documentation

hash_child()

void hash_child ( afp_child_t ** htable, afp_child_t * child )

inlinestatic

kill_child()

int kill_child ( afp_child_t * child )

static

send kill to a child processes

server_child_add()

afp_child_t * server_child_add	(	server_child_t *	children,
		pid_t	pid,
		int	ipc_fd )

add a child

Returns

pointer to struct server_child_data on success, NULL on error

server_child_alloc()

server_child_t * server_child_alloc

(

int

connections

)

initialize server_child structure

server_child_free()

void server_child_free

(

server_child_t *

children

)

free everything

by using a hash table, this increases the cost of this part over a linked list by the size of the hash table

server_child_kill()

void server_child_kill	(	server_child_t *	children,
		int	sig )

send signal to all child processes

server_child_kill_one_by_id()

void server_child_kill_one_by_id	(	server_child_t *	children,
		pid_t	pid,
		uid_t	uid,
		uint32_t	idlen,
		char *	id,
		uint32_t	boottime )

see if there is a process for the same mac

if the times don't match mac has been rebooted

server_child_login_done()

void server_child_login_done	(	server_child_t *	children,
		pid_t	pid,
		uid_t	uid )

server_child_remove()

int server_child_remove	(	server_child_t *	children,
		pid_t	pid )

remove a child and free it

server_child_resolve()

afp_child_t * server_child_resolve	(	server_child_t *	childs,
		id_t	pid )

server_child_transfer_session()

int server_child_transfer_session	(	server_child_t *	children,
		pid_t	pid,
		uid_t	uid,
		int	afp_socket,
		uint16_t	DSI_requestID )

Try to find an old session and pass socket.

Returns

-1 on error, 0 if no matching session was found, 1 if session was found and socket passed

server_reset_signal()

void server_reset_signal

(

void

)

reset children signals

unhash_child()

void unhash_child ( afp_child_t * child )

inlinestatic
