Re: Net::Services

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

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'; }` [download] 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 [download] Is this what you were looking for? -- `g r i n d e r`	[reply] [d/l] [select]

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
