3.2.65 getservbyport

getservbyport PORT, PROTO

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

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

In scalar context, getservbyport returns only the service port name.
