SHUTDOWN(2)                Linux Programmer's Manual               SHUTDOWN(2)



NAME
       shutdown - shut down part of a full-duplex connection

SYNOPSIS
       #include <&lt;sys/socket.h>&gt;

       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,  fur-
       ther  receptions will be disallowed.  If how is SHUT_WR, further trans-
       missions will be disallowed.  If how is SHUT_RDWR,  further  receptions
       and transmissions will be disallowed.

RETURN VALUE
       On  success,  zero is returned.  On error, -1 is returned, and errno is
       set appropriately.

ERRORS
       EBADF  s is not a valid descriptor.

       ENOTCONN
              The specified socket is not connected.

       ENOTSOCK
              s is a file, not a socket.

CONFORMING TO
       POSIX.1-2001, 4.4BSD (the shutdown() function call  first  appeared  in
       4.2BSD).

NOTES
       The  constants  SHUT_RD,  SHUT_WR,  SHUT_RDWR  have  the value 0, 1, 2,
       respectively, and are defined in &lt;sys/socket.h&gt; since glibc-2.1.91.

SEE ALSO
       connect(2), socket(2)
