NAME

POSIX::Socket - Low-level perl interface to POSIX sockets

SYNOPSIS

 use POSIX::Socket
 
 my $rd=_socket(AF_INET, SOCK_DGRAM, 0) or die "socket: $!\n";
 my $wr=_socket(AF_INET, SOCK_DGRAM, 0) or die "socket: $!\n";
 
 my $addr = sockaddr_in(0, inet_aton("127.0.0.1"));
 my $bind_rv=_bind($rd, $addr);
 
 _getsockname($rd, $addr);
 my ($port, $ip) = unpack_sockaddr_in($addr);
 $ip = inet_ntoa($ip);
 die "_getsockname fail!" unless $ip eq "127.0.0.1";
 
 my $ret_val1 = _sendto($wr, $msg, $flags, $addr);
 my $ret_val2 = _recv($rd, $buf, 8192, 0);
 
 _close ($rd);
 _close ($wr);

DESCRIPTION

The primary purpose of this is to use file descriptors instead of file handles for socket operations. File descriptors can be shared between threads and not need dup file handles for each threads.

I hope you enjoyed it.
