if(fd<0)
{
perror("Open");
return 0;
}


char c;
int s;

while(1)
{
s=read(fd,&c,1);
if(!s)
break;
printf("%c",c);
}

printf("\n\n");

close(fd);

}

Write Pipe :

#include<unistd.h>

#include<fcntl.h>

#include<error.h>

int main()

{

int fd;

fd = open("MyPipe",O_WRONLY,0666);

if(fd<0)

{

perror("Open");

return 0;

}

char c[]="Welcome";

int s;

s=write(fd,c,7);

printf("\n\n");
