Function Documentation

◆ _dbus_connection_add_timeout_unlocked()

dbus_bool_t _dbus_connection_add_timeout_unlocked	(	DBusConnection *	connection,
		DBusTimeout *	timeout
	)

Adds a timeout using the connection's DBusAddTimeoutFunction if available.

Otherwise records the timeout to be added when said function is available. Also re-adds the timeout if the DBusAddTimeoutFunction changes. May fail due to lack of memory. The timeout will fire repeatedly until removed. Connection lock should be held when calling this.

Parameters

connection	the connection.
timeout	the timeout to add.

Returns: TRUE on success.

Definition at line 871 of file dbus-connection.c.

◆ _dbus_connection_add_watch_unlocked()

dbus_bool_t _dbus_connection_add_watch_unlocked	(	DBusConnection *	connection,
		DBusWatch *	watch
	)

Adds a watch using the connection's DBusAddWatchFunction if available.

Otherwise records the watch to be added when said function is available. Also re-adds the watch if the DBusAddWatchFunction changes. May fail due to lack of memory. Connection lock should be held when calling this.

Parameters

connection	the connection.
watch	the watch to add.

Returns: TRUE on success.

Definition at line 747 of file dbus-connection.c.

◆ _dbus_connection_block_pending_call()

void _dbus_connection_block_pending_call ( DBusPendingCall * pending )

Blocks until a pending call times out or gets a reply.

Does not re-enter the main loop or run filter/path-registered callbacks. The reply to the message will not be seen by filter callbacks.

Returns immediately if pending call already got a reply.

Parameters

pending the pending call we block for a reply on

◆ _dbus_connection_close_if_only_one_ref()

void _dbus_connection_close_if_only_one_ref ( DBusConnection * connection )

Used internally to handle the semantics of dbus_server_set_new_connection_function().

If the new connection function does not ref the connection, we want to close it.

A bit of a hack, probably the new connection function should have returned a value for whether to close, or should have had to close the connection itself if it didn't want it.

But, this works OK as long as the new connection function doesn't do anything crazy like keep the connection around without ref'ing it.

We have to lock the connection across refcount check and close in case the new connection function spawns a thread that closes and unrefs. In that case, if the app thread closes and unrefs first, we'll harmlessly close again; if the app thread still has the ref, we'll close and then the app will close harmlessly. If the app unrefs without closing, the app is broken since if the app refs from the new connection function it is supposed to also close.

If we didn't atomically check the refcount and close with the lock held though, we could screw this up.

Parameters

connection the connection

Definition at line 2160 of file dbus-connection.c.

References _dbus_assert, _dbus_atomic_get(), CONNECTION_LOCK, and DBusConnection::refcount.

◆ _dbus_connection_close_possibly_shared()

void _dbus_connection_close_possibly_shared ( DBusConnection * connection )

Closes a shared OR private connection, while dbus_connection_close() can only be used on private connections.

Should only be called by the dbus code that owns the connection - an owner must be known, the open/close state is like malloc/free, not like ref/unref.

Parameters

connection the connection

Definition at line 1962 of file dbus-connection.c.

References _dbus_assert, _dbus_current_generation, CONNECTION_LOCK, and NULL.

◆ _dbus_connection_do_iteration_unlocked()

void _dbus_connection_do_iteration_unlocked	(	DBusConnection *	connection,
		DBusPendingCall *	pending,
		unsigned int	flags,
		int	timeout_milliseconds
	)

Queues incoming messages and sends outgoing messages for this connection, optionally blocking in the process.

Each call to _dbus_connection_do_iteration_unlocked() will call select() or poll() one time and then read or write data if possible.

The purpose of this function is to be able to flush outgoing messages or queue up incoming messages without returning control to the application and causing reentrancy weirdness.

The flags parameter allows you to specify whether to read incoming messages, write outgoing messages, or both, and whether to block if no immediate action is possible.

The timeout_milliseconds parameter does nothing unless the iteration is blocking.

If there are no outgoing messages and DBUS_ITERATION_DO_READING wasn't specified, then it's impossible to block, even if you specify DBUS_ITERATION_BLOCK; in that case the function returns immediately.

If pending is not NULL then a check is made if the pending call is completed after the io path has been required. If the call has been completed nothing is done. This must be done since the _dbus_connection_acquire_io_path releases the connection lock for a while.

Called with connection lock held.

Parameters

connection	the connection.
pending	the pending call that should be checked or NULL
flags	iteration flags.
timeout_milliseconds	maximum blocking time, or -1 for no limit.

◆ _dbus_connection_get_message_to_send()

DBusMessage * _dbus_connection_get_message_to_send ( DBusConnection * connection )

Gets the next outgoing message.

Parameters

connection the connection.

Returns: the message to be sent.

Definition at line 613 of file dbus-connection.c.

References _dbus_list_get_last(), and DBusConnection::outgoing_messages.

◆ _dbus_connection_get_next_client_serial()

dbus_uint32_t _dbus_connection_get_next_client_serial ( DBusConnection * connection )

Allocate and return the next non-zero serial number for outgoing messages.

This method is only valid to call from single-threaded code, such as the dbus-daemon, or with the connection lock held.

Parameters

connection the connection

Returns: A suitable serial number for the next message to be sent on the connection.

◆ _dbus_connection_get_pending_fds_count()

Return how many file descriptors are pending in the loader.

Parameters

connection the connection

◆ _dbus_connection_handle_watch()

dbus_bool_t _dbus_connection_handle_watch	(	DBusWatch *	watch,
		unsigned int	condition,
		void *	data
	)

A callback for use with dbus_watch_new() to create a DBusWatch.

Parameters

watch	the watch.
condition	the current condition of the file descriptors being watched.
data	must be a pointer to a DBusConnection

Returns: FALSE if the IO condition may not have been fully handled due to lack of memory
