Hello, I have a bit of legacy code that I want to avoid changing as much as possible:

  my $iaddr = &inet_aton("$sname") || return 5;
  socket(SH,PF_INET,SOCK_STREAM,getprotobyname('tcp'));
  connect(SH,sockaddr_in($port,$iaddr))
    || return 6;

The issue is that I want to modify the amount of time that I am spending waiting for the connect before I timeout. I think that I can use setsockopt to do this. Reading the unix setsockopt (2) manpage (Using FreeBSD 4.1.1-STABLE), it appears that there are two variables associated with timeouts:

           SO_SNDTIMEO        set timeout value for output
           SO_RCVTIMEO        set timeout value for input

My Questions:

  1. Do either of these affect the timeout for a connect or do they only apply to connected sockets?
  2. If not, what is the correct way to set the connect timeout (if it can be done)?
  3. According to man setsockopt, these options require a timeval struct in c to work, what is the correct data structure to modify these options with the perl setsockopt?

Note: Yes, I know, I could do all this so much easier with IO::Socket, but let's just assume that is not an option here.

Thanks!
