ipc

问题 Im new to zmq. Im using the same for local IPC in a Linux based OS (The socket is AF_UNIX type) But I could not find a way to get the caller's (client) process Id. Is there any way to find the same using zmq ? (Finding the pid of the caller is must for my access control requirement and if zmq does not provide the same then I should switch to dbus) Please help me. 回答1: Forget most of the low-level socket designs and worries. Think higher in the sky. ZeroMQ is a pretty higher-level messaging

问题 I am coming from a bit of Mac background. I am trying to do some simple IPC. I am making a script for an application which always scripts to run ctypes during runtime. Thus I am able to use the C libs like Objective-C and Win32API. This application which I am writing script for has two individual processes. Users of my script run it in both instances as a "hook"/"module" so to speak. It is not an injection, it is ctypes-like run during run time. Pretty cool. I need to send a string from

问题 This question already has an answer here : Reading from a process, StreamReader.Peek() not working as expected (1 answer) Closed 3 years ago . I am having trouble setting up a c# application that creates and interacts with a python process1. A simplistic example is given below. EDIT: Further research on SO unveiled that my question is a possible duplicate. A potentially related known bug in the .NET Framework is duscussed here and here. It seems that back in 2014 the only easy workaround is

问题 I actually don't know whether I am asking a proper question. Let me describe my problem first. End user <-1-> web server (by PHP) <-2-> an internal process (by C or C++) <-3-> an external hardware The 1 should be something like ajax request. The 2 should be something like inter-process communication. The 3 should be uart RS232 communication. The end user will request to change some settings on the hardware, then the request will propagate to the hardware. The hardware replies successful or

问题 This question already has answers here : Passing arguments one by one one in console exe by c# code (3 answers) Closed 6 years ago . I am running a console application exe (developed in c#) by my another windows application in c# . Process p = Process.Start("strExePath"); The console application which i ran expects some user inputs and I want to provide those user inputs by the c# code of windows application which runs the console exe file. How can I achieve this? 回答1: You can redirect the

问题 I have successfully set up the password less ssh between the servers and my computer. There is a simple openMPI program which is running well on the single computer. But ,unfortunately when i am trying this on a cluster ,neither i am getting a password prompt(as i have set up ssh authorization) nor the execution is moving forward. Hostfile looks like this, # The Hostfile for Open MPI # The master node, 'slots=8' is used because it has 8 cores localhost slots=8 # The following slave nodes are

问题 I'm attempting to implement IPC, but what I'm doing is somewhat different from the documentation I've seen. I need to asynchronously send, receive, and respond with a service and form application. //Service1.cs serverPipe = new NamedPipeServerStream(@"testpipe", PipeDirection.InOut, 1, PipeTransmissionMode.Message, PipeOptions.Asynchronous); //LoginForm.cs clientPipe = new NamedPipeClientStream(@".", @"testpipe", PipeDirection.InOut PipeOptions.Asynchronous); I believe this sets up both sides

问题 I've been asked to develop the consumer (client) side to a producer (server), where the producer creates processes, waits until the consumer has read shared memory and deleted processes, then passes control back to the producer for the killing of processes and the shutting down of the shared memory block. I've researched the difference between sleep and wait, and realise that as soon as fork() is called, the child process begins running. The below code is after the creation of processes and

问题 Introduction and general objective This question originated from this one where I was trying to send image data from the child to the parent. The problem in that case was using buffered and unbuffered read functions. You can find working code of the old question at the bottom of this one. Now I am trying to send an image from a parent process to the child process (generated by calling popen from the parent) that is supposed to show the iamge. The image is a grayscale png image. It is opened

问题 I am writing an implementation for doing IPC. User do a call, I take all these parameters and pass them onto other process. I have written an automatic code generator for such functions based on logic which works something like this : Take all the parameters and put them inside a structure. Add other information required for IPC. Pass the size and pointer of this struct to POSIX message queue. Data from this address, till the size specified, is read and send to other process. De-construct the
