ipc

问题 Java/Android - I am unable to find any Worker Thread to Worker Thread communication examples. The examples always involve the UiThread. I have a HandlerThread that gets fed work and the HandlerThread spreads the work onto multiple worker threads. I want the multiple worker threads to communicate back to the HandlerThread. All I have been able to do is have the worker threads communicate with the UiThread via Handler. Thanks! 回答1: public class ModelFragment extends Fragment implements Handler

问题 I would like to use IPC::Run to communicate with child via child's STDIN, STDOUT and STDERR (start, pump, finish). It seems to work. I would like to know how to detect premature child exit (e.g. caused by errors) pipes closed by the child 回答1: The pump throws a die on errors, or writes its message to STDERR if " called after all harnessed activities have completed ." See right before ROUTINES section and pump itself. The second case can come about if the child exited. So wrap the pump call in

问题 Let say we have a server application written in Python. Let also say that this main server process forked two more processes at the startup. Server awaits its clients, and when one comes decides to which of two forked processes should pass the client's socket. I do not want to fork a process each time a client comes; I want to have fixed number of servers, but one main server that receives a connection, then pass it to a server that deals with a specific work client asked for. This should be

问题 I've coded some relatively simple communication protocol using shared memory, and shared mutexes. But then I wanted to expand support to communicate between two .dll's having different run-time in use. It's quite obvious that if you have some std::vector<__int64> and two dll's - one vs2010, one vs2015 - they won't work politely with each other. Then I've thought - why I cannot serialize in ipc manner structure on one side and de-serialize it on another - then vs run-times will work smoothly

问题 I am trying to use a named pipe for communication within a process. Here is the code #include <stdio.h> #include <fcntl.h> #include <signal.h> void sigint(int num) { int fd = open("np", O_WRONLY); write(fd, "y", 1); close(fd); } main() { char ch[1]; int fd; mkfifo("np", 0666); signal(SIGINT, sigint); fd = open("np", O_RDONLY); read(fd, ch, 1); close(fd); printf("%c\n", ch[0]); return; } What I want is for main to block till something is written to the pipe. The problem is that the signal

问题 I'm working on what should (hopefully) be a small feature for a .NET software solution that will allow one application to report on the status of multiple instances of another application running on more than one computer on the same network. I took a look at this MSDN article on named pipes, and set up a simple client/server project that worked great. However, this was only two processes running on the same computer (so for the NamedPipeClientStream constructor, I passed "." as the

问题 I have a written Linux device (implement as a interface) and a perl script, I need those two to communicate among them while executing(perl to device). I have thought of writing to a file and reading from it. but i think it is not an ideal one. can any one point me to more good solution. 回答1: In addition to the methods Joachim mentioned also look into creating a character or block device so you can access it through /dev/somenode. That's probably the preferred way if your driver is really

问题 This Q&A refers to and can be used for foll. purposes: Send message from IE browser to vb6 app via ActiveX dll Send message from ActiveX dll to vb6 app Send message from C#.net (dll) to vb6 app I have read this article but doesn't seem to be very clear for my purpose... I have also referred to this article to create ActiveX object and have implemented an ActiveX dll that I am calling from browser to launch an application on client side.. The dll checks whether the VB6 exe (process) is running

问题 I need to have a communication channel between my web application that runs on Chrome, and a native code on Windows. I need to run a native code when JS requests and pass the results back from native code. The environment is totally managed so I can set trusts and group policies, etc. I can think of preparing a small web service that runs locally (and allows CORS) and call this service from javascript, but in this case i need to run this code forever. Any advices will be very helpful. If it

问题 Suppose I have no network card installed on my computer, and I would like to have functionality similar to the following: Process 1 will publish messages to some URI, say "Uri1" var publisher = new Publisher("Uri1"); publisher.publish(new Message("Somedata"); Process 2 will both listen for messages on "Uri1" and publish messages to "Uri2" var subscriber = new Subscriber("Uri1") subscriber.MessageReceived += data => Console.Writeline(data.ToString()); var publisher = new Publisher("Uri2")
