Net::protoent(3)       Perl Programmers Reference Guide	      Net::protoent(3)

NAME
       Net::protoent - by-name interface to Perl's built-in getproto*() func‐
       tions

SYNOPSIS
	use Net::protoent;
	$p = getprotobyname(shift ⎪⎪ '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(shift ⎪⎪ 'tcp') ⎪⎪ die "no proto";
	print "proto for $p_name is $p_proto, aliases are @p_aliases\n";

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

       You may also import all the structure fields directly into your names‐
       pace 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 "p_".  Thus, "$proto_obj->name()" cor‐
       responds to $p_name if you import the fields.  Array references are
       available as regular array variables, so for example "@{
       $proto_obj->aliases() }" would be simply @p_aliases.

       The getproto() function is a simple front-end that forwards a numeric
       argument to getprotobyport(), and the rest to getprotobyname().

       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.

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