I'm trying to create a create one parent process and ONE child process that repeatedly pass … I have a chunk of code where I am trying to split a problem into N subproblems across N child processes, having each process do work with its given subproblem, then … I'm having trouble understanding pipe and fork, at least implementing it in practice. /q9 inputString Parent: writing to pipe 'inputString' Task read input from terminal into the parent-to-child pipe. In a sense, the parent/child thing is just a distraction; they're different processes that can use standard IPC mechanisms to … Today we are going to see, how can we use pipes and fork system call for creating multiple processes and handling our work.

While Node‘s … Named pipes are a type of interprocess communication (IPC) mechanism that allow data to be exchanged between two or more processes on a computer.
