[linux-dvb] Pipe?

["Andrea Gerardi" <gerardi_andre79@hotmail.com>]

Hi list,
I need use pipe to analyze consecutive pid of ts. With this code:

if(pid=fork()<0) perror("\nfork error\n");

	else if (pid>0)
	{//parent
		close(fd[0]);
		//tuning operation and get fd_dvr handle

	       close(fd[1]);
if (waitpid(pid,NULL,0)<0) perror("waitpid error");
		exit(0);

	}
	else if (pid==0)
	{//child
		close(fd[1]);

		close(fd[0]);
		exit(0);
	}
