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 (pid0)
{//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);
}
