call_context

cancel_lock

template<typename ProxyServer , typename CallContext_ >

Lock* mp::ServerInvokeContext< ProxyServer, CallContext_ >::cancel_lock {nullptr}

For IPC methods that execute asynchronously, not on the event-loop thread: lock preventing the event-loop thread from freeing the params or results structs if the request is canceled while the worker thread is reading params (call_context.getParams()) or writing results (call_context.getResults()).

req

template<typename ProxyServer , typename CallContext_ >

int mp::ServerInvokeContext< ProxyServer, CallContext_ >::req

Definition at line 50 of file proxy-io.h.

request_canceled

template<typename ProxyServer , typename CallContext_ >

bool mp::ServerInvokeContext< ProxyServer, CallContext_ >::request_canceled {false}

For IPC methods that execute asynchronously, not on the event-loop thread, this is set to true if the IPC call was canceled by the client or canceled by a disconnection.

If the call runs on the event-loop thread, it can't be canceled. This should be accessed with cancel_lock held if it is not null, since in the asynchronous case it is accessed from multiple threads.
