Detailed Description

data structures and utility functions for child processes

most of the implementation is in libatalk/util/server_child.c

Macro Definition Documentation

ASP_RUNNING

#define ASP_RUNNING   (1 << 10)

CHILD_HASHSIZE

#define CHILD_HASHSIZE   32

Typedef Documentation

afp_child_t

typedef struct afp_child afp_child_t

Function Documentation

server_child_add()

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

extern

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 )

extern

initialize server_child structure

server_child_free()

void server_child_free ( server_child_t *  children )

extern

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_handler()

void server_child_handler ( server_child_t *  )

extern

server_child_kill()

void server_child_kill ( server_child_t *  children, int  sig  )

extern

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  )

extern

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, const char *  client_address  )

extern

server_child_remove()

int server_child_remove ( server_child_t *  children, pid_t  pid  )

extern

remove a child and free it

server_child_resolve()

afp_child_t * server_child_resolve ( server_child_t *  childs, id_t  pid  )

extern

server_child_set_session_token()

int server_child_set_session_token ( server_child_t *  children, pid_t  pid, uid_t  uid, const void *  token, size_t  token_len  )

extern

Store an opaque reconnect token for a child session.

Returns

0 on success, -1 on error

server_child_transfer_session()

int server_child_transfer_session ( server_child_t *  children, uid_t  uid, const void *  token, size_t  token_len, int  afp_socket, uint16_t  DSI_requestID  )

extern

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  )

extern

reset children signals
