igoryonya has asked for the wisdom of the Perl Monks concerning the following question:
I am reading documentation on select command and I can't figure out, what these RBITS,WBITS,EBITS mean.
Well, I came to guess, that probably, RBITS - means Read Bits, WBITS - Write Bits, but what about EBITS, then? select RBITS,WBITS,EBITS,TIMEOUT my ($nfound, $timeleft) = select(my $rout = $rin, my $wout = $win, my $eout = $ein, $timeout);without any explanation.
