SHUTDOWN(3P)            POSIX Programmer's Manual           SHUTDOWN(3P)

ПРЕДИСЛОВИЕ

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

НАЗВАНИЕ

       shutdown — shut down socket send and receive operations

СИНТАКСИС

       #include <sys/socket.h>

       int shutdown(int socket, int how);

ОПИСАНИЕ

       The shutdown() function shall cause all or part of a full-duplex
       connection on the socket associated with the file descriptor
       socket to be shut down.

       The shutdown() function takes the following arguments:

       socket      Specifies the file descriptor of the socket.

       how         Specifies the type of shutdown. The values are as
                   follows:

                   SHUT_RD     Disables further receive operations.

                   SHUT_WR     Disables further send operations.

                   SHUT_RDWR   Disables further send and receive
                               operations.

       The shutdown() function disables subsequent send and/or receive
       operations on a socket, depending on the value of the how
       argument.

ЗНАЧЕНИЕ ВОЗВРАЩАЕМОГО ЗНАЧЕНИЯ

       Upon successful completion, shutdown() shall return 0; otherwise,
       -1 shall be returned and errno set to indicate the error.

ОШИБКИ

       The shutdown() function shall fail if:

       EBADF  The socket argument is not a valid file descriptor.

       EINVAL The how argument is invalid.

       ENOTCONN
              The socket is not connected.

       ENOTSOCK
              The socket argument does not refer to a socket.

       The shutdown() function may fail if:

       ENOBUFS
              Insufficient resources were available in the system to
              perform the operation.
