C program for pipe in Linux

Last Updated : 26 Apr, 2018

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);  
}
