NAME

	Netutil, netmkaddr, authfd – Network utility functions

SYNOPSIS

	include "netutil.m"; util := load Netutil Netutil–>PATH; Client, Server: con iota; netmkaddr: fn(addr, net, svc: string): string; authfd:     fn(fd: ref Sys–>FD, role: int, alg, kfile, addr: string): (ref Sys–>FD, string);

DESCRIPTION

Netutil provides functions used in many programs providing or using network services. Netmkaddr is similar to the Plan 9 function of the same name. It builds a network address given a default network to use, net , and a default service name, svc . Authfd performs Client or Server authentication (according to the role indicated) on the fd given. The alg, kfile, and addr parameters may be left as nil if desired. They correspond to the algorithm used, the keyfile used, and the address to authentify for. The function returns a file descriptor (perhaps encrypted using alg), and a string with authentication information. Upon error, the system error string is updated and a null descriptor returned.
