Thanks Janes... I am not a C developer - was not aware about select()... I was read it as some kind of sleep...
Than Clemens explained to me what select() does... However - to me it is just implementation detail... Which is possible in one language, but not in another... But technically, is the loop inside select() - or outside is irrelevant to me (i see the benefit... Though, not sure the benefit - is that big...nowdays.....) >From my point of view - what is important - is the main goal what should be achieved... If with resources what I have (php - though I am not php developer either) I dont have the same power like in another language - who cares - main goal must be achived . things work - or dont, but we must make them work :) I am just curious: LISTEN foo Select() Another client says: NOTIFY bar Will select() - get something from server?
