Communication between processes is valuable in a multitasking operating system to enable concurrent processes to work together. Pipes are one of three forms within OS/2 of interprocess communication (IPC) and the only form available for IPC from a DOS application running in a VDM to an OS/2 application.
This chapter describes how to create, manage, and use named pipes for IPC of a DOS application in a VDM to an OS/2 program. Pipes enable two or more processes to communicate as if they were reading from and writing to a file.
