SHUTDOWN(2)                BSD 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
     disallowed. If how is SHUT_RDWR, further sends and receives will be
     disallowed.

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").
