flush
Description:
Asynchronously flushes this, that is, writes all queued outgoing messages to the transport and then flushes the transport (using flush_async).
This is useful in programs that want to emit a D-Bus signal and then exit immediately. Without flushing the connection, there is no guarantee that the message has been sent to the networking buffers in the OS kernel.
This is an asynchronous method. When the operation is finished, callback will be invoked in the thread-default main context (see [
method@GLib.MainContext.push_thread_default]) of the thread you are calling this method from. You can then call flush.end
to get the result of the operation. See flush_sync for the
synchronous version.
Parameters:
| this | |
| cancellable |
a Cancellable or null |
| callback |
a TaskReadyCallback to call when the request is satisfied or null if you don't care about the result |
| user_data |
The data to pass to |
