Typedef Documentation

DBusServerSocket

typedef struct DBusServerSocket DBusServerSocket

Opaque object representing a Socket server implementation.

Definition at line 46 of file dbus-server-socket.c.

Function Documentation

_dbus_server_listen_socket()

DBusServerListenResult _dbus_server_listen_socket	(	DBusAddressEntry *	entry,
		DBusServer **	server_p,
		DBusError *	error
	)

Tries to interpret the address entry for various socket-related addresses (well, currently only tcp and nonce-tcp).

Sets error if the result is not OK.

Parameters

entry	an address entry
server_p	a new DBusServer, or NULL on failure.
error	location to store rationale for failure on bad address

Returns

the outcome

_dbus_server_listen_unix_socket()

DBusServerListenResult _dbus_server_listen_unix_socket	(	DBusAddressEntry *	entry,
		DBusServer **	server_p,
		DBusError *	error
	)

Tries to interpret the address entry for UNIX socket addresses.

Sets error if the result is not OK.

Parameters

entry	an address entry
server_p	location to store a new DBusServer, or NULL on failure.
error	location to store rationale for failure on bad address

Returns

the outcome

_dbus_server_new_for_domain_socket()

DBusServer * _dbus_server_new_for_domain_socket	(	const char *	path,
		dbus_bool_t	abstract,
		DBusError *	error
	)

Creates a new server listening on the given Unix domain socket.

Parameters

path	the path for the domain socket.
abstract	TRUE to use abstract socket namespace
error	location to store reason for failure.

Returns

the new server, or NULL on failure.

_dbus_server_new_for_socket()

DBusServer * _dbus_server_new_for_socket	(	DBusSocket *	fds,
		int	n_fds,
		const DBusString *	address,
		DBusNonceFile *	noncefile,
		DBusError *	error
	)

Creates a new server listening on the given file descriptor.

The file descriptor should be nonblocking (use _dbus_set_fd_nonblocking() to make it so). The file descriptor should be listening for connections, that is, listen() should have been successfully invoked on it. The server will use accept() to accept new client connections.

Parameters

fds	list of file descriptors.
n_fds	number of file descriptors
address	the server's address
noncefile	to be used for authentication (NULL if not needed)
error	location to store reason for failure

Returns

the new server, or NULL on OOM or other error.

_dbus_server_new_for_tcp_socket()

DBusServer * _dbus_server_new_for_tcp_socket	(	const char *	host,
		const char *	bind,
		const char *	port,
		const char *	family,
		DBusError *	error,
		dbus_bool_t	use_nonce
	)

Creates a new server listening on TCP.

If host is NULL, it will default to localhost. If bind is NULL, it will default to the value for the host parameter, and if that is NULL, then localhost If bind is a hostname, it will be resolved and will listen on all returned addresses. If family is NULL, hostname resolution will try all address families, otherwise it can be ipv4 or ipv6 to restrict the addresses considered.

Parameters

host	the hostname to report for the listen address
bind	the hostname to listen on
port	the port to listen on or 0 to let the OS choose
family
error	location to store reason for failure.
use_nonce	whether to use a nonce for low-level authentication (nonce-tcp transport) or not (tcp transport)

Returns

the new server, or NULL on failure.

_dbus_server_socket_own_filename()

void _dbus_server_socket_own_filename	(	DBusServer *	server,
		char *	filename
	)

This is a bad hack since it's really unix domain socket specific.

Also, the function weirdly adopts ownership of the passed-in string.

Parameters

server	a socket server
filename	socket filename to report/delete
