Raku port of Perl's Net::servent module
use Net::servent; $s = getservbyname('ftp') || die "no service"; printf "port for %s is %s, aliases are %s\n", $s.name, $s.port, "@_aliases"; use Net::servent qw(:FIELDS); getservbyname('ftp') || die "no service"; print "port for $s_name is $s_port, aliases are @s_aliases\n";
This module tries to mimic the behaviour of Perl's
Net::servent module as closely as possible in the Raku Programming Language.
This module's exports
getservent functions that return
Net::servent objects. This object has methods that return the similarly named structure field name from the C's servent structure from servdb.h, stripped of their leading "s_" parts, namely name, aliases, port and proto.
You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. Access these fields as variables named with a preceding s_ in front their method names. Thus, $serv_obj.name corresponds to $s_name if you import the fields.
getserv function is a simple front-end that forwards a numeric argument to
getservbyport and the rest to
This module depends on the availability of POSIX semantics. This is generally not available on Windows, so this module will probably not work on Windows.
