|
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.

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.

|
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. Called with connection lock held.
