Subject: Re: [plug] Perl: handling blocking reads "nicely"
2. using either select or poll function...
computationally expensive. :P
no :-> select or poll is least expensive if you have multiple descriptors
watching on it versus to other techniques which is more expensive :->
if you dont want to implement socket timeout... you can set the socket
filedescriptor default from blocking state into non-block state using
O_NONBLOCK flag in fcntl() function...
O_NONBLOCK is worse. now THAT's real polling. CPU hog. MS-DOS style
coding. :)
nope :-> non-blocking technique has its own placed :-> one good example is
non-blocking connect() for a web client :->
fooler.
