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?

    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. =cut

    Is this what you were looking for?
