3.2.64 getservbyname

getservbyname NAME, 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.
