Thread: Need Help in Creating Pipes in Linux

Hi

I was trying to learn pipe but I the program is not giving me the expected output.

The program is as below:

Code:

//#include <iostream>
#include<stdio.h>
#include<stdlib.h>
#include<errno.h>
#include<sys/types.h>
#include<unistd.h>
#include<unistd.h>
#include <string.h>



int main(int argc, char **argv) {
  int pfd[2];
  char buf[30];
  pipe(pfd);
  
  if(fork())
  {
    printf("\n Child writing to pipe");
    write(pfd[0],"Testing Pipe",24);
    printf("\n Child exiting\n");
    exit(0);
  }
  
  else{
    memset(buf,0x00,sizeof(buf));
    printf("\n Parent Reading");
    read(pfd[1],buf,5);
    printf("\n PArent REad %s\n",buf);
    
  }
  
    return 0;
}

Can Anybody help me what I am doing wrong?

Thanks
