typedef struct ipc_header ipc_header_t

Function Documentation

ipc_child_state()

int ipc_child_state	(	AFPObj *	obj,
		uint16_t	state )

ipc_child_write()

int ipc_child_write	(	int	fd,
		uint16_t	command,
		int	len,
		void *	msg )

ipc_get_session()

int ipc_get_session ( struct ipc_header * ipc, server_child_t * children )

static

ipc_kill_token()

int ipc_kill_token ( struct ipc_header * ipc, server_child_t * children )

static

ipc_login_done()

int ipc_login_done ( const struct ipc_header * ipc, server_child_t * children )

static

ipc_server_read()

int ipc_server_read	(	server_child_t *	children,
		int	fd )

Read a IPC message from a child

This is using an fd with non-blocking IO, so EAGAIN is not an error

Parameters

children	(rw) pointer to our structure with all childs
fd	(r) IPC socket with child

Returns

-1 on error, 0 on success

ipc_set_state()

int ipc_set_state ( struct ipc_header * ipc, server_child_t * children )

static

ipc_set_volumes()

int ipc_set_volumes ( struct ipc_header * ipc, server_child_t * children )

static
