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

LIBRARY
     Standard C Library (libc, -lc)

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 the file descriptor s to be shut down.  The how
     argument specifies the type of shutdown.  Possible values are:

     SHUT_RD	further receives will be disallowed.

     SHUT_WR	further sends will be disallowed.

     SHUT_RDWR	further sends and receives will be disallowed.

RETURN VALUES
     The shutdown() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS
     The shutdown() call fails if:

     [EBADF]		The s argument is not a valid file descriptor.

     [EINVAL]		The how argument is invalid.

     [ENOTCONN]		The socket is not connected.

     [ENOTSOCK]		The s argument does not refer to a socket.

SEE ALSO
     connect(2), socket(2)

STANDARDS
     The shutdown() function is expected to comply with IEEE Std 1003.1g-2000
     (“POSIX.1”), when finalized.

HISTORY
     The shutdown() function call appeared in 4.2BSD.  The SHUT_RD, SHUT_WR,
     and SHUT_RDWR constants appeared in IEEE Std 1003.1g-2000 (“POSIX.1”).
