C program for pipe in Linux
Working and implementation of Pipe in Linux.
Prerequisite : Pipe in Linux
Approach : Pipe is highly used in Linux. Basically, pipe has 2 parts, one part is for writing and another is used for reading. So, an array of size 2 is taken. a[1] is used for writing and a[0] for reading.After reading from pipe, program will show output on console.
// C program to implement pipe in Linux#include <errno.h>#include <fcntl.h>#include <stdio.h>#include <stdlib.h>#include <sys/wait.h>#include <unistd.h> int main(){ // array of 2 size a[0] is for reading // and a[1] is for writing over a pipe int a[2]; // opening of pipe using pipe(a) char buff[10]; if (pipe(a) == -1) { perror("pipe"); // error in pipe exit(1); // exit from the program } // writing a string "code" in pipe write(a[1], "code", 5); printf("\n"); // reading pipe now buff is equal to "code" read(a[0], buff, 5); // it will print "code" printf("%s", buff); } |
