Study Notes

Pipes in Interprocess Communication

In ordinary pipes, a pair of communicating processes must have a parent-child relationship.
In Windows, ordinary pipes are referred to as anonymous pipes.
The main limitation of ordinary pipes is that they can only be used for one-way communication.
A named pipe allows bidirectional communication without requiring a parent-child relationship between processes.

Characteristics of Named Pipes

Named pipes are provided for communication between unrelated processes.
The main difference between ordinary (Unnamed) pipes and named pipes is that named pipes can be accessed from outside the process that created them, and allow for bidirectional communication.
In the context of communication using pipes, 'full-duplex' means that data can be sent and received simultaneously.

Buffering in Message Systems

Automatic buffering in message systems allows for efficient transmission of messages, as it reduces the overhead of transmitting small messages.
A system with 'zero-capacity' buffering means that there is no buffer space available for storing messages.

Named Pipes in UNIX Systems

Named Pipes on UNIX systems allow for bidirectional, half-duplex transmission.
Named Pipes on UNIX systems are referred to as FIFOs (First-In-First-Out).
The system call mkfifo() is used to create Named Pipes on UNIX systems.

Named Pipes in Windows Systems

Named Pipes on Windows systems allow for bidirectional, full-duplex transmission.
The function CreateNamedPipe() is used to create Named Pipes on Windows systems.
Two pipes are typically needed for two-way communication using Named Pipes on UNIX systems.
