in reply to Net::Services

In light of the fact that this code requires socket capability, is there something I can add, say in a BEGIN block or via 'use' that would check that the system can support sockets at compile-time, as opposed to the run-time error message that one gets when the servent methods are used?

It's not what you know, but knowing how to find it if you don't know that's important

Re:x2 Net::Services (use Config?)

    Do you mean something along the lines of:

      use Config;
  BEGIN {
    die "You are socketless!\n"
      unless Config::config_vars(qw/d_socket/) eq 'define';
  }

    If you need really specific socket capabilities there is any number of fine-grained tests you could perform. Randomly cutting and pasting from perldoc Config gives things like

    =over
     `d_getsbyname'
         From d_getsrvby.U:

         This variable conditionally defines the
         `HAS_GETSERVBYNAME' symbol, which indicates to the C
         program that the getservbyname() routine is available to
         look up services by their name.

    Is this what you were looking for?
