 | | In this chapter, we examined a number of techniques that allow two processes on the same computer to communicate. For related processes (parent and child), pipes are the most common and widespread solution, although others may be used. For unrelated processes, FIFOs (in the System V world) and UNIX-domain sockets (in the Berkeley world) are the most common. The so-called System V IPC functions, while sometimes convenient, have a number of drawbacks, and should probably be avoided unless absolutely necessary. | |
