HP-UX Reference (11i v2 07/12) - 2 System Calls (vol 5)

g
getsockopt(2) getsockopt(2)
should follow the X/Open specification (see xopen_networking(7)).
FUTURE DIRECTION
Currently, the default behavior is the HP-UX BSD Sockets; however, it might be changed to X/Open
Sockets in a future release. At that time, any HP-UX BSD Sockets behavior that is incompatible with
X/Open Sockets might be obsoleted. Applications that conform to the X/Open specification now will avoid
migration problems (see xopen_networking(7)).
AUTHOR
getsockopt() and setsockopt() were developed by HP and the University of California, Berkeley.
