Net::servent
Returns information for an Internet service. Overrides
the core getservent, getservbyname, and getservbyport functions, replacing them with
versions that return Net::servent objects. The functions take a
default second argument of tcp. The
objects have methods that return the fields of the same name from the
servent structure in
netdb.h:
Field | Description |
|---|---|
| List of aliases |
| Name of service |
| Port |
| Protocol to use |
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 s_
to the field name:
$serv_obj->name( ) $s_name
