Networking

• New networking interface functions

In IRIX 6.5.17, support for following interfaces has been added:

– For nodename-to-address and address-to-nodename translations,

getaddrinfo(3), getnameinfo(3), gai_strerror(3),

freeaddrinfo(3), getipnodebyname(3),

getipnodebyaddr(3) and freehostent(3)

– For interface index-to-name and name-to-index conversions,

if_indextoname(3), if_nametoindex(3), if_nameindex(3)

and if_freenameindex(3)

These interfaces perform the following functions:

– The getaddrinfo() function translates the node name and/or a

service name and returns a set of socket addresses and associated

information. This is used in creating a socket with which to

address the speciﬁed service. It can provide the functionality of

gethostbyname() and getservbyname().

– The getnameinfo() function translates a socket address to a

node name and a service location.

The above translations are done in a protocol-independent manner to

support both IPv4 and IPv6. (Note that IPv6 is not supported in this

IRIX release.)

– The gai_strerror() function returns a text string describing an

error that is returned by getaddrinfo() or getnameinfo().
