Net::servent - phpMan

NAME
    Net::servent - by-name interface to Perl's built-in getserv*() functions

SYNOPSIS
     use Net::servent;
     $s = getservbyname(shift || 'ftp') || die "no service";
     printf "port for %s is %s, aliases are %s\n",
        $s->name, $s->port, "@{$s->aliases}";

     use Net::servent qw(:FIELDS);
     getservbyname(shift || 'ftp') || die "no service";
     print "port for $s_name is $s_port, aliases are @s_aliases\n";

DESCRIPTION
    This module's default exports override the core getservent(),
    getservbyname(), and getnetbyport() functions, replacing them with
    versions that return "Net::servent" objects. They take default second
    arguments of "tcp". This object has methods that return the similarly
    named structure field name from the C's servent structure from netdb.h;
    namely name, aliases, port, and proto. The aliases method returns an
    array reference, the rest scalars.

    You may also import all the structure fields directly into your
    namespace as regular variables using the :FIELDS import tag. (Note that
    this still overrides your core functions.) Access these fields as
    variables named with a preceding "s_". Thus, "$serv_obj->name()"
    corresponds to $s_name if you import the fields. Array references are
    available as regular array variables, so for example "@{
    $serv_obj->aliases()}" would be simply @s_aliases.

    The getserv() function is a simple front-end that forwards a numeric
    argument to getservbyport(), and the rest to getservbyname().

    To access this functionality without the core overrides, pass the "use"
    an empty import list, and then access function functions with their full
    qualified names. On the other hand, the built-ins are still available
    via the "CORE::" pseudo-package.

EXAMPLES
     use Net::servent qw(:FIELDS);

     while (@ARGV) {
         my ($service, $proto) = ((split m!/!, shift), 'tcp');
         my $valet = getserv($service, $proto);
         unless ($valet) {
             warn "$0: No service: $service/$proto\n"
             next;
         }
         printf "service $service/$proto is port %d\n", $valet->port;
         print "alias are @s_aliases\n" if @s_aliases;
     }

NOTE
    While this class is currently implemented using the Class::Struct module
    to build a struct-like class, you shouldn't rely upon this.
