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

s
socket(2) socket(2)
[EPROTOTYPE] The type of socket and protocol do not match.
[ESOCKTNOSUPPORT] The specified socket type is not supported in this address family.
[ETIMEDOUT] Connection timed out.
WARNINGS
Not all possible errno values are documented in each socket related manpage due to dependencies from
the underlying protocol modules. Refer to the errno(2) manpage for a complete list of error codes.
IPv6 is supported on HP-UX 11i Version 1.0, with the optional IPv6 software installed. Currently, IPv6 is
not supported on systems running HP-UX 11i Version 1.6.
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
