SHUTDOWN(2) OpenBSD Programmer's Manual SHUTDOWN(2) NAME shutdown - shut down part of a full-duplex connection SYNOPSIS #include <sys/types.h> #include <sys/socket.h> int shutdown(int s, int how); DESCRIPTION The shutdown() call causes all or part of a full-duplex connection on the socket associated with s to be shut down. If how is SHUT_RD, further re- ceives will be disallowed. If how is SHUT_WR, further sends will be dis- allowed. If how is SHUT_RDWR, further sends and receives will be disal- lowed. RETURN VALUES A 0 is returned if the call succeeds, -1 if it fails. ERRORS The call succeeds unless: [EINVAL] how is not SHUT_RD, SHUT_WR, or SHUT_RDWR. [EBADF] s is not a valid descriptor. [ENOTSOCK] s is a file, not a socket. [ENOTCONN] The specified socket is not connected. SEE ALSO connect(2), socket(2) HISTORY The shutdown() function call appeared in 4.2BSD. The how arguments used to be simply 0, 1, and 2, but now have named values as specified by X/Open Portability Guide Issue 4 (``XPG4''). OpenBSD 3.4 June 4, 1993 1
