Interesting, it is documented in RFC 2133/2553/4038 and from the man
page it appears to be intended as a GNU-extension, but it is not
mentioned in POSIX or the Glibc manual. I wonder how portable it is?
An old Solaris host I looked at had it. Maybe something for the Austin
group...
NOTES
In order to assist the programmer in choosing reasonable sizes for the
supplied buffers, <netdb.h> defines the constants
#define NI_MAXHOST 1025
#define NI_MAXSERV 32
Since glibc 2.8, these definitions are exposed only if one of the fea‐
ture test macros _BSD_SOURCE, _SVID_SOURCE, or _GNU_SOURCE is defined.
The former is the constant MAXDNAME in recent versions of BIND's
<arpa/nameser.h> header file. The latter is a guess based on the ser‐
vices listed in the current Assigned Numbers RFC.
