Detailed Description

"Backend" for a DBusConnection.

Types and functions related to DBusTransport. A transport is an abstraction that can send and receive data via various kinds of network connections or other IPC mechanisms.

Typedef Documentation

Opaque object representing a way message stream.

DBusTransport abstracts various kinds of actual transport mechanism, such as different network protocols, or encryption schemes.

Definition at line 33 of file dbus-transport.h.

Function Documentation

dbus_bool_t _dbus_transport_can_pass_unix_fd ( DBusTransport transport)

Returns TRUE if the transport supports sending unix fds.

Parameters
transportthe transport
Returns
TRUE if TRUE it is possible to send unix fds across the transport.

void _dbus_transport_disconnect ( DBusTransport transport)

Closes our end of the connection to a remote application.

Further attempts to use this transport will fail. Only the first call to _dbus_transport_disconnect() will have an effect.

Parameters

void _dbus_transport_do_iteration ( DBusTransport transport,
unsigned int  flags,
int  timeout_milliseconds 
)

Performs a single poll()/select() on the transport's file descriptors and then reads/writes data as appropriate, queueing incoming messages and sending outgoing messages.

This is the backend for _dbus_connection_do_iteration(). See _dbus_connection_do_iteration() for full details.

Parameters
transportthe transport.
flagsindicates whether to read or write, and whether to block.
timeout_millisecondsif blocking, timeout or -1 for no timeout.

dbus_bool_t _dbus_transport_try_to_authenticate ( DBusTransport transport)

Returns TRUE if we have been authenticated.

If we have not finished authenticating, but we have enough buffered input to finish the job, then this function will do so before it returns.

This used to be called _dbus_transport_get_is_authenticated(), but that name seems inappropriate for a function with side-effects.

Todo:
we drop connection->mutex when calling the unix_user_function, and windows_user_function, which may not be safe really.
Parameters
transportthe transport
Returns
whether we're authenticated
