Implementation details of DBusTransport on sockets.

Typedef Documentation

DBusTransportSocket

typedef struct DBusTransportSocket DBusTransportSocket

Opaque object representing a socket file descriptor transport.

Definition at line 49 of file dbus-transport-socket.c.

Function Documentation

_dbus_transport_new_for_domain_socket()

DBusTransport * _dbus_transport_new_for_domain_socket	(	const char *	path,
		dbus_bool_t	abstract,
		DBusError *	error
	)

Creates a new transport for the given Unix domain socket path.

This creates a client-side of a transport.

Parameters

path	the path to the domain socket.
abstract	TRUE to use abstract socket namespace
error	address where an error can be returned.

Returns

a new transport, or NULL on failure.

_dbus_transport_new_for_socket()

DBusTransport * _dbus_transport_new_for_socket	(	DBusSocket	fd,
		const DBusString *	server_guid,
		const DBusString *	address
	)

Creates a new transport for the given socket file descriptor.

The file descriptor must be nonblocking (use _dbus_set_fd_nonblocking() to make it so). This function is shared by various transports that boil down to a full duplex file descriptor.

Parameters

fd	the file descriptor.
server_guid	non-NULL if this transport is on the server side of a connection
address	the transport's address

Returns

the new transport, or NULL if no memory.

_dbus_transport_new_for_tcp_socket()

DBusTransport * _dbus_transport_new_for_tcp_socket	(	const char *	host,
		const char *	port,
		const char *	family,
		const char *	noncefile,
		DBusError *	error
	)

Creates a new transport for the given hostname and port.

If host is NULL, it will default to localhost

Parameters

host	the host to connect to
port	the port to connect to
family	the address family to connect to
noncefile	path to nonce file
error	location to store reason for failure.

Returns

a new transport, or NULL on failure.

_dbus_transport_open_socket()

DBusTransportOpenResult _dbus_transport_open_socket	(	DBusAddressEntry *	entry,
		DBusTransport **	transport_p,
		DBusError *	error
	)

Opens a TCP socket transport.

Parameters

entry	the address entry to try opening as a tcp transport.
transport_p	return location for the opened transport
error	error to be set

Returns

result of the attempt

_dbus_transport_open_unix_socket()

DBusTransportOpenResult _dbus_transport_open_unix_socket	(	DBusAddressEntry *	entry,
		DBusTransport **	transport_p,
		DBusError *	error
	)

Opens a UNIX socket transport.

Parameters

entry	the address entry to try opening as a unix transport.
transport_p	return location for the opened transport
error	error to be set

Returns

result of the attempt
