Returns information for an Internet protocol.
Overrides the core getprotoent, getprotobyname, and
getprotobynumber functions with object-oriented versions that return
Net::protoent objects. The functions take a default second argument of
tcp. The objects have methods that return the
fields of the same name from the protoent structure in netdb.h:
| Field | Description |
|---|---|
aliases | List of aliases |
name | Name of host |
proto | Protocol |
You can access the structure fields either with the methods or by
importing the fields into your namespace with the :FIELDS import tag and
then accessing them by prepending p_ to the field name:
$proto_obj->name() $p_name
