Have a look at the
post_accept() routine in
Server.pm in the module
Net::Server. You might even find
Net::Server is exactly what you are looking for (as it has all the code for creating a daemon, and then switching the socket to STDIN/STDOUT before handing it to your callback function).
Something along the lines of:
if( defined $fileno ){
open STDIN, "<&$fileno"
or die "Couldn't open STDIN to the client socket: $!";
open STDOUT, ">&$fileno"
or die "Couldn't open STDOUT to the client socket: $!";
} else {
*STDIN= \*{ $sock };
*STDOUT= \*{ $sock };
}
STDIN->autoflush(1);
STDOUT->autoflush(1);
(untested).
