Windows Named Pipe

"Named Pipeline" or "named Pipeline" (Named Pipes) is a simple inter-process communication (I P C) mechanism, Microsoft Windows NT, Windows 2000, windows 95 and Windows 98 both provide support for it (but do not include Windows CE ).

A named pipe supports reliable, one-way, or two-way data communication between different processes on the same computer or across different computers on a network. use named pipelines to design applicationsProgramIt is very simple, and you do not need to have a thorough understanding of the basic network transfer protocol (such as t c p/I p or I p x. this is because the named pipe uses the Microsoft network provider (Ms n p) redirector to establish communications between processes through a network. in this way, the application does not have to care about the details of the network protocol. one important reason for using named pipes as your network communication solution is that they fully utilize the security features built in Windows NT and Windows 2000.

Here is an example of an acceptable command pipeline. suppose we want to develop a data management system that only allows a specified user group to operate. imagine you have a computer in your office, which stores company secrets. we require that only company administrators can access and handle these secrets. assume that on your workstation machine, every employee in the company can see the computer on the network. however, we do not want ordinary employees to gain access to confidential materials. in this case, the named pipe can play a very good role, because we can develop a server application, so that the request from the client prevails, the company's secret security operations. the server can restrict customer access to management personnel. This can be easily achieved by using the security mechanisms provided by Windows NT or the new version of Windows 2000.
