Read MoreDifference between Pipes and Message Queues
Pipes and Message Queues are both Inter-Process Communication (IPC) mechanisms in Unix/Linux systems. Pipes provide a simple unidirectional byte stream between processes, while message queues provide a more flexible, bidirectional mechanism for exchanging discrete messages with optional priorities. Unix Pipes A pipe provides a unidirectional flow of data between processes. It is created using the pipe() function, which returns two file descriptors − one for reading and one for writing. Both the sender and receiver processes must be running simultaneously for a pipe to function. Message Queues A message queue allows a sender process to write ...
