Thread: pipeline troubles

Hi, I am attempting to create a program to make 3 child processes, the first child places 20 integers into the pipeline, the second child places another 2 integers into the pipeline and the thrid child reads all the data from the pipeline. i dunno who but thsi program has just gone totally wrong, could someone give me some advice on it please as my lectures are less that helpful.

Code:

#include<stdio.h>
#include<unistd.h>

int main()
{
	int fd[3][2],i,j;
	char odd[54];
	char even[59];
	char buffer[113];
	char buffer2[113];
	pipe(fd);
	if(fork() == 0)
	{
		if(fork() == 0)
		{
			if(fork() == 0)
			{
				i = 0;
				j = 0;
				while(i < 20)
				{
					sprintf(even,"%d",j);
					write(fd[2][1],even,sizeof(even));
					i = i + 1;
					j = i + 1;
				}
				exit(0);
			}
			 i = 1;
			 j = 1;
			while(i < 21)
			{
				sprintf(odd,"%d",j);
				write(fd[1][1],odd,sizeof(odd));
				i = i + 1;
				j = i + 1;
			}
			exit(0);
		}
		read(fd[2][0],buffer,sizeof(buffer));
		printf("%s\n",buffer);
		read(fd[1][0],buffer2,sizeof(buffer2));
		printf("%s\n",buffer2);
	}
return 0;
}

Thanks Qui

solved it myself nm.
