Raku port of Perl's Net::protoent module
use Net::protoent;
my $p = getprotobyname('tcp') || die "no proto";
printf "proto for %s is %d, aliases are %s\n",
$p.name, $p.proto, "$p.aliases()";
use Net::protoent qw(:FIELDS);
getprotobyname('tcp') || die "no proto";
print "proto for $p_name is $p_proto, aliases are @p_aliases\n";
This module tries to mimic the behaviour of Perl's Net::protoent module as closely as possible in the Raku Programming Language.
This module's exports getprotobyname, getprotobynumber, and getprotoent functions that return Netr::protoent objects. This object has methods that return the similarly named structure field name from the C's protoent structure from netdb.h, stripped of their leading "p_" parts, namely name, aliases, 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 p_ in front their method names. Thus, $proto_obj.name corresponds to $p_name if you import the fields.
The getproto function is a simple front-end that forwards a numeric argument to getprotobynumber and the rest to getprotobyname.
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.
