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

shutdown(2) shutdown(2)

still leaving the socket descriptor open, so that the caller can receive back any data SCTP was unable to

deliver.

Note: SCTP is only available when the SCTP optional bundle is installed.

RETURN VALUE

Upon successful completion, shutdown() returns 0. Otherwise it returns

-1 and errno is set to indi-

cate the error.

ERRORS

shutdown() fails if any of the following conditions are encountered:

[EBADF] s is not a valid ﬁle descriptor.

[EINVAL]

HP-UX BSD Sockets only. The speciﬁed socket is not connected.

[EINVAL]

_XOPEN_SOURCE_EXTENDED only.

The how argument is invalid.

[ENOTCONN]

_XOPEN_SOURCE_EXTENDED only.

The speciﬁed socket is not connected.

[ENOPROTOOPT] The remote system or an intermediate system in the communications path does not

support a protocol option sent by the local system. This option may have been set

using a

getsockopt or setsockopt() call, or set as a system parameter.

[ENOTSOCK] s is a valid ﬁle descriptor, but it is not a socket.

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)).
