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 with the methods or by importing the fields into your namespace with the :FIELDS import tag and accessing them by prepending p_ to the field name:
$proto_obj->name( ) $p_name
