PROTO

This function does the same thing as getservbyname (3): it translates a service (port) name to its corresponding port number. PROTO is a protocol name such as "tcp" . The return value in list context is:

($name, $aliases, $port_number, $protocol_name)

In scalar context, getservbyname returns only the service port number.
