Overview

Package netdb provides a Go interface for the protoent and servent structures as defined in netdb.h

A pure Go implementation is used by parsing /etc/protocols and /etc/services

All return values are pointers that point to the entries in the original list of protocols and services. Manipulating the entries would affect the entire program.

Variables

var (
	Protocols []*Protoent
	Services  []*Servent
)

These variables get populated from /etc/protocols and /etc/services respectively.

Types

type Protoent

type Protoent struct {
	Name    string
	Aliases []string
	Number  int
}

func GetProtoByName

func GetProtoByName(name string) (protoent *Protoent)

GetProtoByName returns the Protoent whose name or any of its aliases matches the argument.

func GetProtoByNumber

func GetProtoByNumber(num int) (protoent *Protoent)

GetProtoByNumber returns the Protoent for a given protocol number.

func (*Protoent) Equal

func (this *Protoent) Equal(other *Protoent) bool

Equal checks if two Protoents are the same, which is the case if their protocol numbers are identical or when both Protoents are nil.

type Servent

type Servent struct {
	Name     string
	Aliases  []string
	Port     int
	Protocol *Protoent
}

func GetServByName

func GetServByName(name string, protocol *Protoent) (servent *Servent)

GetServByName returns the Servent for a given service name or alias and protocol. If the protocol is nil, the first service matching the service name is returned.

func GetServByPort

func GetServByPort(port int, protocol *Protoent) *Servent

GetServByPort returns the Servent for a given port number and protocol. If the protocol is nil, the first service matching the port number is returned.

func (*Servent) Equal

func (this *Servent) Equal(other *Servent) bool

Equal checks if two Servents are the same, which is the case if their port numbers and protocols are identical or when both Servents are nil.
