da, no ako trqbva da se chete opredeleno kolichestvo samo ot edin file
select() e overkill. 

primerno 

/* install signal handler somewhere */

alarm(10);
a=fgets(buff,10,f)

ili perl:  
            
        my $result=eval {
                my $r;
                local $SIG{ALRM} = sub { die "timeout" };
                alarm shift;
                $r=<$DEVICE>;
                alarm 0;
                return $r;
        }; 

za vsichki ostanali sluchai sum suglasen za select() :)
