C Program For Ipc Using Pipes
Bilal Rabbani 5-Feb-14 2:47 5-Feb-14 2:47 Wonderful job Sir, it helped me alot understanding Named Pipes, but I need some help here. I noticed that C# code can send a complete string perfectly but C++ code cannot send SPACE ' ', If I write 'Hello I'm C++ Code' it will send only 'Hello' and Then 'I'm' then 'C++', it divides the string into chunks.
Also it miss some chunks too. Could u please help me out with this, It would be highly appreciated. EDIT: Fixed, the issue is in scanf () method, it actually divide the buffer into chunks! Regards B.Rabbani.

If I run your code in Visual Studio 2012 and set the compiler mode to release, the first message sends the client into an infinite loop. I just cannot seem to figure out why. It also receives nothing, the fSuccess flag comes back true, but no bytes are ever recieved. Flash Player Activex Is Not Installed Apex Dvx-811 User Manual here. there. Do you have any idea why this is and if this is the C++ or C# part's fault? Other than this, great article, helped me a lot!
I have been looking through the posts for fork, pipe, dup2, and IPC. Linux Programming; IPC between 2 programs using pipe; Getting started with C or C++. C Program to implement Inter Process Communication(IPC) by using Pipe at 10:38 AM. Posted by Techman.
Regards, Matija Edit: I did a bit of checking, the C# client works fine under Debug or Release mode, so my money is on the C++ part. It seems to go haywire when optimization is turned on. Any ideas on how to fix this? Thank you again. Edit2: To do a follow up, the problem was in the c++ part, while passing the pipe handle to another thread to be exact. I got it fixed on my own. Thank you for the wonderful example code though.
The Windows operating system provides mechanisms for facilitating communications and data sharing between applications. Collectively, the activities enabled by these mechanisms are called interprocess communications (IPC). Some forms of IPC facilitate the division of labor among several specialized processes. Other forms of IPC facilitate the division of labor among computers on a network. Typically, applications can use IPC categorized as clients or servers. A client is an application or a process that requests a service from some other application or process. A server is an application or a process that responds to a client request.
Many applications act as both a client and a server, depending on the situation. For example, a word processing application might act as a client in requesting a summary table of manufacturing costs from a spreadsheet application acting as a server. The spreadsheet application, in turn, might act as a client in requesting the latest inventory levels from an automated inventory control application.
After you decide that your application would benefit from IPC, you must decide which of the available IPC methods to use. It is likely that an application will use several IPC mechanisms. The answers to these questions determine whether an application can benefit by using one or more IPC mechanisms. • Should the application be able to communicate with other applications running on other computers on a network, or is it sufficient for the application to communicate only with applications on the local computer? • Should the application be able to communicate with applications running on other computers that may be running under different operating systems (such as 16-bit Windows or UNIX)? • Should the user of the application have to choose the other applications with which the application communicates, or can the application implicitly find its cooperating partners? • Should the application communicate with many different applications in a general way, such as allowing cut-and-paste operations with any other application, or should its communications requirements be limited to a restricted set of interactions with specific other applications?
